Abstract:

The electronic and lattice properties of α-TiNX (X:F, Cl, Br, I) were investigated from first principles. Ab initio calculations for geometry optimization, electronic band structure and zone-center phonon calculations have been carried out by using plane-wave pseudopotential method which is not examined before. From the electronic structure calculation, band gaps have been found as 1.23 eV, 0.955 eV, 0.897 eV for TiNF , TiNCl , TiNBr while there is no band gap for TiNI . This result can separate TiNI from other metal nitride halides which are semiconductor. Band structure calculations showed that increasing the electropositivity of halogen atom in TiNX systems decreasing the fermi energy level or in other words shift the valance bonds to higher energy. Also zone center phonon modes show that the vibrational frequencies are increasing by atomic number of halogens. Heavier halogen atom makes the system vibrate more slowly and as expected to reduce vibrational frequency.

Abstract:

Abstract The peculiarities of the formation of zinc and nickel(II) complexes by interaction of metal powder or metal oxide with ammonium salts (halides, nitrate, thiocyanate) were investigated in non-aqueous solutions (methanol, acetonitrile, N,N-dimethylformamide=DMF, dimethylsulfoxide=DMSO) in presence of 1,4-diazabicyclo[2.2.2]octane. The stoichiometry of the com plexes was found to depend on the initial reagent ratio Ni/ZnO:NH4X and Ni/ZnO:Ten. The compounds of compositions Zn(HTen)(H2O)(NO3)3 and Ni(HTen)(Ten)Cl3 were characterized by X-ray crystallography. Both complexes contain five-coordinate metal atoms. The zinc compound possesses monomeric molecular structure whilst the nickel complex is polymeric.

In the composition of the explosive-atmoelectrogenic paragenes studied by us, more than 100 mineral species, varieties and non-crystalline phases are found - carbon minerals, phases and compounds, native metals and alloys, carbides, silicides, nitrides, halides, chalcogenides, oxides, silicates and aluminosilicates, oxygen salts. The studied paragenes is characterized by an abnormally low level of mineralogical organization, which indicates the deep origin of the substance in the explosive facies of volcanic eruptions, including carbon minerals, phases and organic compounds.

Abstract:

The ligands Ph2PCH2P(Se)Ph2 ( dpmSe ) and Ph2AsCH2CH2P(Se)Ph2 ( apeSe ) have been treated with Group 6 metal pentacarbonyl halo anions, [M(C0)5X]-, the Group 6 hexacarbonyls and the carbonyl halides M(C0)4X2 (M = Mo, W, X = C1, Br). Reaction of both dpmSe and apeSe with the anions [M(C0)5X]- in the presence of silver nitrate gave the complexes M(CO)5(L-L′) (L-L′ = dpmSe or apeSe ) with the ligand coordinated in a monodentate fashion through the Group 15 donor atom. Reaction of dpmSe with the hexacarbonyls gave only M(C0)4( dpmSe ) with the ligand chelated but, in contrast, apeSe could not be chelated to metal(0) and acted only as a monodentate ligand. These differences are rationalized in terms of the structure of the ligands. The behaviour of the ligands is much more similar in the metal(11) carbonyl halide chemistry. Both formed a mixture of two isomers of M(CO)3(L-L′)X2 (L-L′= dpmSe, apeSe ) in which the ligands are chelated . In the apeSe system, n.m.r. studies show these isomers are in an equilibrium which varies with temperature at a rate which is slow on the n.m.r. timescale, but the dpmSe complexes do not interchange. On reaction with further ligand, only one of the isomers of M(CO)3( dpmSe )X2 reacts to give incomplete formation of the dicarbonyl Mo(Co)2( dpmSe )2X2, which has one dpmSe ligand chelated and the other monodentate through phosphorus. On the other hand, for the apeSe system quantitative formation of Mo(CO)2( apeSe )2X2 was observed. For the apeSe system only, bubbling CO through a solution of M(CO)2( apeSe )2X2 gave M(CO)3( apeSe )2X2 with the ligands monodentate through arsenic. Extensive 31P and 77Se n.m.r. studies are described.

Full text

Abstract:

Tantalum oxynitrides, such as TaON, exhibit promising color properties and can be employed as nontoxic yellow pigments containing no heavy metals. We have developed a process for preparing nitrides or oxynitrides involving the vacuum-calcination of a precursor material obtained via reaction between a metal halide and liquidNH3. Herein, we describe the synthetic conditions of the liquid-NH3process that affect the color, and thus the color characteristics, of the resulting pigments. Reaction and postreaction treatment conditions were adjusted to obtain the desired yellow color. The liquid-NH3process was performed using 1.0 eq ofH2O(relative toTaCl5) as the oxygen source and 30.0 eq of KCl (relative toTaCl5) as flux. Calcination of the precursor at 1073 K under vacuum was followed by recalcination from room temperature to 973 K at rate of 10 Kmin−1under air. A powder with a color index ofL∗=84.20,a∗=−2.71, andb∗=44.07was obtained.

Full text

Abstract:

Metal halide perovskites are known to suffer from rapid degradation, limiting their direct applicability. Here, the degradation of phenethylammonium lead iodide (PEA2PbI4) two-dimensional perovskites under ambient conditions was studied using fluorescence, absorbance, and fluorescence lifetime measurements. It was demonstrated that the long-term stability of two-dimensional perovskites could be achieved through the encapsulation with hexagonal boron nitride. While un-encapsulated perovskite flakes degraded within hours, the encapsulated perovskites were stable for at least three months. In addition, encapsulation considerably improved the stability under laser irradiation. The environmental stability, combined with the improved durability under illumination, is a critical ingredient for thorough spectroscopic studies of the intrinsic optoelectronic properties of this material platform.

Abstract:

The outstanding optoelectronic performance and facile synthetic approach of metal halide perovskites has inspired additional applications well beyond efficient solar cells and light emitting diodes (LEDs). Herein, we present an alternative option available for the optimisation of selective and efficient oxidation of benzylic alcohols through photocatalysis. The materials engineering of hybrids based on formamidine lead bromide (FAPbBr3) and graphic carbon nitride (g-C3N4) is achieved via facile anti-solvent approach. The photocatalytic performance of the hybrids is highly reliant on weight ratio between FAPbBr3 and g-C3N4. Besides, the presence of g-C3N4 dramatically enhances the long-term stability of the hybrids, compared to metal oxides hybrids. Detailed optical, electrical and thermal studies reveal the proposed novel photocatalytic and stability behaviours arising in FAPbBr3 and g-C3N4 hybrid materials.

Abstract:

Silver is, along with gold and the platinum-group metals, one of the so called precious metals. Because of its comparative scarcity, brilliant white color, malleability and resistance to atmospheric oxidation, silver has been used in the manufacture of coins and jewelry for a long time. Silver has the highest known electrical and thermal conductivity of all metals and is used in fabricating printed electrical circuits, and also as a coating for electronic conductors. It is also alloyed with other elements such as nickel or palladium for use in electrical contacts. The most useful silver salt is silver nitrate, a caustic chemical reagent, significant as an antiseptic and as a reagent in analytical chemistry. Pure silver nitrate is an intermediate in the industrial preparation of other silver salts, including the colloidal silver compounds used in medicine and the silver halides incorporated into photographic emulsions. Silver halides become increasingly insoluble in the series: AgCl, AgBr, AgI. All silver salts are sensitive to light and are used in photographic coatings on film and paper. The ZORKA-PHARMA company (Sabac, Serbia) specializes in the production of pharmaceutical remedies and lab chemicals. One of its products is chemical silver nitrate (argentum-nitricum) (l). Silver nitrate is generally produced by dissolving pure electrolytically refined silver in hot 48% nitric acid. Since the purity of silver nitrate, produced in 2002, was not in compliance with the p.a. level of purity, there was doubt that the electrolytically refined silver was pure. The aim of this research was the gravimetric and volumetric determination of the purity of electrolytically refined silver and silver nitrate, produced industrially and in a laboratory. The purity determination was carried out gravimetrically, by the sedimentation of silver(I) ions in the form of insoluble silver salts: AgCl, AgBr and Agi, and volumetrically, according to Mohr and Volhardt. The purity of electrolytically refined silver obtained volumetrically, according to Volhard, was 99.49%. The results suggest that the purity of electrolytically refined silver was higher than 99%. After all of these determinations, the purity of electrolytically refined silver was examined by atomic absorption spectrometry and the results confirmed that the purity of electrolytically refined silver was 99.99%. Electrolytically refined silver contained other metals: Mn, Cu, Fe, Zn, Pb, Cd, and the contents of these metals were: 1.15 ppm; 0.75 ppm; 0.65 ppm; 1.82 ppm; < 0.07 ppm and < 0.01 ppm, respectively.

A variety of 3,4-disubstituted pyridine derivatives with a tert-butyl group in the 4-position were synthesized in a transition-metal-free, two-step reaction sequence from 3-substituted pyridine precursors. Highly regioselective addition of t-Bu2Mg to TIPS-activated pyridines and an efficient microwave-assisted aromatization with sulfur as oxidant afforded the desired 3,4-disubstituted pyridine derivatives in moderate to excellent yields. The method is compatible with many functional groups such as ester, amide, halide, nitrile or alkyne groups present in the 3-position.

Abstract:

The structural chemistry of the polymeric 1:1 adducts of copper(1) halides ( CuX ; X = Cl, Br, I) with nitrile bases (exemplified by aceto- and benzo-nitrile ) has been systematically explored. Single-crystal X-ray structure redeterminations of enhanced precision have been carried out for all acetonitrile adducts (refined as orthorhombic, Pbnm , Z 4, a ≈ 13.0, b ≈ 8.5, c ≈ 4.0 � ; R 0.039, 0.030, 0.043 for No = 534, 365, 727 'observed' reflections) and the chloride and bromide benzonitrile adducts (monoclinic, P21/n, a ≈ 3.9, b ≈ 17.5, c ≈10.9 � , β ≈ 98, Z 4); R 0.046, 0.048 for No = 1452, 1209); all structures are of the common one-dimensional 'stair' polymer type. In these adducts, the ligand is essentially 'one-dimensional' with substituents well removed from the point of attachment and from interaction within the parent polymer chain. Under these circumstances, the polymer is essentially 'orthogonal' with Cu-X crosslinks at (or nearly at) right angles to the polymer axis, and containing quasi-mirror planes, the series providing reference parameters for the description of distortions observed in these polymers when more hindered bases are coordinated.

Abstract:

Three new metal(II)–cytosine (Cy)/5-fluorocytosine (5FC) complexes, namely bis(4-amino-1,2-dihydropyrimidin-2-one-κN 3)diiodidocadmium(II) or bis(cytosine)diiodidocadmium(II), [CdI2(C4H5N3O)2], (I), bis(4-amino-1,2-dihydropyrimidin-2-one-κN 3)bis(nitrato-κ2 O,O′)cadmium(II) or bis(cytosine)bis(nitrato)cadmium(II), [Cd(NO3)2(C4H5N3O)2], (II), and (6-amino-5-fluoro-1,2-dihydropyrimidin-2-one-κN 3)aquadibromidozinc(II)–6-amino-5-fluoro-1,2-dihydropyrimidin-2-one (1/1) or (6-amino-5-fluorocytosine)aquadibromidozinc(II)–4-amino-5-fluorocytosine (1/1), [ZnBr2(C4H5FN3O)(H2O)]·C4H5FN3O, (III), have been synthesized and characterized by single-crystal X-ray diffraction. In complex (I), the CdII ion is coordinated to two iodide ions and the endocyclic N atoms of the two cytosine molecules, leading to a distorted tetrahedral geometry. The structure is isotypic with [CdBr2(C4H5N3O)2] [Muthiah et al. (2001). Acta Cryst. E57, m558–m560]. In compound (II), each of the two cytosine molecules coordinates to the CdII ion in a bidentate chelating mode via the endocyclic N atom and the O atom. Each of the two nitrate ions also coordinates in a bidentate chelating mode, forming a bicapped distorted octahedral geometry around cadmium. The typical interligand N—H...O hydrogen bond involving two cytosine molecules is also present. In compound (III), one zinc-coordinated 5FC ligand is cocrystallized with another uncoordinated 5FC molecule. The ZnII atom coordinates to the N(1) atom (systematic numbering) of 5FC, displacing the proton to the N(3) position. This N(3)—H tautomer of 5FC mimics N(3)-protonated cytosine in forming a base pair (via three hydrogen bonds) with 5FC in the lattice, generating two fused R 2 2(8) motifs. The distorted tetrahedral geometry around zinc is completed by two bromide ions and a water molecule. The coordinated and nonccordinated 5FCs are stacked over one another along the a-axis direction, forming the rungs of a ladder motif, whereas Zn—Br bonds and N—H...Br hydrogen bonds form the rails of the ladder. The coordinated water molecules bridge the two types of 5FC molecules via O—H...O hydrogen bonds. The cytosine molecules are coordinated directly to the metal ion in each of the complexes and are hydrogen bonded to the bromide, iodide or nitrate ions. In compound (III), the uncoordinated 5FC molecule pairs with the coordinated 5FC ligand through three hydrogen bonds. The crystal structures are further stabilized by N—H...O, N—H...N, O—H...O, N—H...I and N—H...Br hydrogen bonds, and stacking interactions.

Abstract:

Single crystal X-ray structure determinations have been executed for several title compounds of the mononuclear form [LMX2], namely [(bpy)ZnX2], X=Cl, Br; [(phen)ZnX2], X=Cl, Br, I (bpy=2,2′-bipyridine; phen=1,10-phenanthroline). Also reported are the crystal structures of ZnSO4/bpy/H2O (1:1:5) (≡ [(bpy)Zn(OH2)4](SO4)·H2O) and Zn(NO3)2/bpy/H2O (1:1:3) (≡ [(bpy)Zn(OH2)3(ONO2)](NO3)). The sulfate complex completes the array [LM(OH2)4]2+, L=bpy, phen, M=Zn, Cd, while the nitrate is the first nitrate example for [LM(OH2)3(OX)](+) (OX=ONO2, OSO3). In all examples of the sulfate and nitrate forms here and previously defined, the metal atoms are six-coordinate, with any anionic donors lying in axial coordination sites (i.e. M–O (quasi-) normal to the LM plane). The structures of [LHg(SCN)2] (L=phen, tpy) (tpy=2,2′:6′,2′-terpyridine), [(tpy)(CdBr2], and [Zn(tpy)2](NO3)2·2H2O are also recorded.

The structures form an interesting contrast with those of their silver(I)/phosphorus analogues, of similar symmetry but with a and c interchanged, as is the metal · · · metal axis orientation which, in each case, lies parallel to the long crystallographic axis. An unsolvated nitrate [(Ph3As)2Cu(µ-O-ONO2)2Cu(AsPh3)2], monoclinic, P 21/c, a 14·867(8), b 23·518(8), c 21·86(1) Å, β 122·24(4)°, Z = 4 dimers, R 0·056 for No 3447, is also recorded, the structure being similar to that of its silver(I) bromide analogue. The far-infrared spectra of [(Ph3As)2Cu(µ-X)2Cu(AsPh3)2].2CHCl3 (X = Cl, Br) show v(CuX) bands at 195 and 153 cm-1 respectively. Shifts in the wavenumbers of the CHCl3 vibrations which involve the hydrogen atom (or the deuterium atom in the corresponding CDC13 compounds) are in the direction expected for hydrogen bonding of the chloroform to the halide ligand, and the magnitudes of the shifts in these and the corresponding Ph3P/AgX complexes appear to be sensitive to the degree of ionic character of the M-X bonds. A combined differential scanning calorimetry/infrared study suggests that the chloroform disolvates are converted into unsolvated compounds which have the same halogen-bridged dimeric structures as the parent compounds, with v(CuX) = 184, 141 cm-1 for X = Cl, Br respectively.

Abstract:

Gold nanoparticles covered with a mixture of ligands of which one type contains solubilizing triethylene glycol residues and the other peripheral zinc(II)–dipicolylamine (DPA) complexes allowed the optical detection of hydrogenphosphate, diphosphate, and triphosphate anions in water/methanol 1:2 (v/v). These anions caused the bright red solutions of the nanoparticles to change their color because of nanoparticle aggregation followed by precipitation, whereas halides or oxoanions such as sulfate, nitrate, or carbonate produced no effect. The sensitivity of phosphate sensing depended on the nature of the anion, with diphosphate and triphosphate inducing visual changes at significantly lower concentrations than hydrogenphosphate. In addition, the sensing sensitivity was also affected by the ratio of the ligands on the nanoparticle surface, decreasing as the number of immobilized zinc(II)–dipicolylamine groups increased. A nanoparticle containing a 9:1 ratio of the solubilizing and the anion-binding ligand showed a color change at diphosphate and triphosphate concentrations as low as 10 μmol/L, for example, and precipitated at slightly higher concentrations. Hydrogenphosphate induced a nanoparticle precipitation only at a concentration of ca. 400 μmol/L, at which the precipitates formed in the presence of diphosphates and triphosphates redissolved. A nanoparticle containing fewer binding sites was more sensitive, while increasing the relative number of zinc(II)–dipicolylamine complexes beyond 25% had a negative impact on the limit of detection and the optical response. Transmission electron microscopy provided evidence that the changes of the nanoparticle properties observed in the presence of the phosphates were due to a nanoparticle crosslinking, consistent with the preferred binding mode of zinc(II)–dipicolylamine complexes with phosphate anions which involves binding of the anion between two metal centers. This work thus provided information on how the behavior of mixed monolayer-protected gold nanoparticles is affected by multivalent interactions, at the same time introducing a method to assess whether certain biologically relevant anions are present in an aqueous solution within a specific concentration range.

Abstract:

Background: Noble-metal nanocrystals have been extensively studied over the past decades because of their unique optical properties. The polyol process is considered an effective method for silver (Ag) nanocrystals’ synthesis in solution even though the reproducibility of its shape controlling is still a challenge. Here, Ag nanowires and nanocubes were synthesized by the polyol process, in which the Ag+ ions are directly reduced by ethylene glycol with a certain amount of Cl− ions added. We present the relationship between the final morphology of the Ag nanostructures with the parameters of reaction, including temperature, growth time, injection rate, and the amount of sodium chloride. The as-synthesized nanowires and nanocubes were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The uniformly distributed nanocubes with a mean edge length of 140 nm were obtained. The localized surface plasmon resonance of Ag nanocubes was characterized by laser scanning fluorescence confocal microscopy. The photoluminescence enhancement was observed on the perovskite film coupled with Ag nanocubes. Objective: We aimed to synthesize uniform and controllable silver nanocubes and nanowires through the polyol process and explore the interaction between CsPbBr3 perovskite film and Ag nanocubes antennas. Methods: We synthesized silver nanocubes and nanowires through the polyol process where the silver nitrate (AgNO3) was reduced by Ethylene Glycol (EG) in the presence of a blocking agent polyvinylpyrrolidone (PVP). Results: We successfully synthesized Ag nanocubes with an average edge length of 140 nm and Ag nanowires with a uniform distribution in terms of both shape and size through a polyol process with sodium chloride (NaCl) as the additive. In addition, the local photoluminescence (PL) enhancement was observed in a perovskite film by combining Ag nanocubes, which is attributed to the antennas plasmonic effect of the Ag nanocubes. Conclusion: In summary we studied the parameters in the polyol process such as reaction temperature, growth time, injection rate, kind of halide ion and NaCl amount for the synthesis of Ag nanowires and nanocubes. Our results suggest that the concentration of Cl- and the growth time have the main influence on Ag nanowires and nanocubes formation. The optimum growth time was found to be 60 min and 120 min for the formation of Ag nanowires and nanocubes, respectively. In addition, we revealed that the opportune reaction temperature of Ag nanowires was 140 °C. The injection rate of precursors was also found to play an important role in the final morphology of Ag nanowires and nanocubes. In addition, for the generation of Ag nanocubes, the presence of Cl− ion in the reaction is critical, which can eliminate most of the byproducts. We obtained the Ag nanowires with a uniform distribution in terms of both shape and size, and nanocubes with average lengths of 140 nm by the polyol process with the optimal parameters. Plasmon-coupled emission induced by noble-metal nanocrystals has attracted more attention in recent years. In this work, the PL of a perovskite film was enhanced by the coupling of Ag nanocubes due to the surface plasmonic effect.

Abstract:

Abstract The reactivity of the chalcogen–nitrogen bond toward main-group element or transition-metal halides, as well as electrophilic and nucleophilic reagents, is the source of a variety of applications of Se–N and Te–N compounds in both inorganic or organic chemistry. The thermal lability of Se–N compounds also engenders useful transformations including the formation of radicals via homolytic Se–N bond cleavage. These aspects of Se–N and Te–N chemistry will be illustrated with examples from the reactions of the binary selenium nitride Se4N4, selenium–nitrogen halides [N(SeCln)2]+ (n = 1, 2), the synthons E(NSO)2 (E = Se, Te), chalcogen–nitrogen–silicon reagents, chalcogen(IV) diimides RN=E=NR, the triimidotellurite dianion [Te(NtBu)3]2−, chalcogen(II) amides and diamides E(NR2)2 (E = Se, Te; R = alkyl, SiMe3), and heterocyclic systems.

Abstract:

Inorganic nitrile halides have been studied theoretically by quantum-chemical approach and experimentally in the reactions of halogenation, nitration and nitro halogenation of aromatic compounds and alkynes. The generation of nitrile halides was eventually proved can be can be carried out using the iodine system (alkali metal halides) in the presence of alkali metal nitrates in an acetic acid medium. It has been found that the reaction can give the products of iodination, nitration, nitro halogenation, as well as products of cyclization, and oxidation depending on the nature of the halogen. To predict the products of reaction theoretical quantum-chemical calculations for intermediate particles – nitrile halides using the standard Gaussian‑03 software package were carried out. The possibility of NO2Hal formation was approved from quantum calculations. Furthermore the geometry of NO2Hal particles and mechanism of their homo- or heterolytic decay were represented

Full text

Abstract:

AbstractThe production of thin or thick films of metals or ceramics by chemical vapour deposition has often been achieved by the use of halide gas precursors. In certain cases, this choice was made purely for reasons of simplicity: gas cylinder available, gas species already used in another field, etc. Experience has subsequently shown, however, that this choice can give rise to significant changes in the nature and proportions of deposited phases. These are highly dependent upon: – the value of the oxidiser:reducer ratio in the gas phase,– the degree of metal oxidation in the halide considered,– possible competition between two reducing agents designed to reduce the halide. These factors, among others, strongly influence the thermochemistry of the deposition reaction. Their roles must therefore be clearly understood, interpreted and predicted by the thermochemical analysis. Based on examples relating to silicide, nitride and boride deposits, an attempt will be made to determine the sensitive parameters and to deduce selection criteria.

All nitrate <em>trans</em> octahedral compounds stabilized a 3D supramolecular arrangement <em>via</em> hydrogen bonding, throughout the nitrate anions, the ligand and the coordinated water molecules; the <em>cis</em>-octahedral halide complex formed a 2D pleated sheet arrangement, by intermolecular π stacking and halide-hydrogen bonding.
