Résumé :
The influence of non-covalent interactions on the crystal packing of molecules is well documented in the literature. Unlike molecular solids, crystal engineering of non-molecular solids is difficult to interpret as aggregation is complicated by the presence of neutral as well as ionic species and a range of forces operating, from weak hydrogen bonding to strong covalent interactions. In this perspective, we demonstrate for the first time the role of non-bonding interactions in the occurrence of oxide, hydroxide, or chloride linkages in oxides, hydroxychlorides, and chlorides of copper-based minerals and coordination polymers in terms of a mechanistic approach based on supramolecular retrosynthesis. The model proposed here visualizes the crystal nucleus as a supramolecular analogue of a transition state wherein appropriate tectons (chemically reasonable molecules) aggregate through non-bonding forces that can be perceived through well-known supramolecular synthons. The mechanistic approach provides chemical insights into the occurrence of different topologies and solid-state phenomena like polymorphism.

Résumé :
In the construction of heterobimetallic coordination polymers based on dithiocarbamato–carboxylate (DTCC ligands), platinum as a thiophilic metal center can be replaced by the cheaper nickel or palladium. The compounds Zn[Pd(HL)2] and Zn2[M(L)2] (M = Ni, Pd; L = {SSC-N(CH2COO)2}3−) were prepared in a sequential approach starting from K3(L). The products were characterized by IR and NMR spectroscopy, thermal analyses, and single-crystal X-ray diffraction. The products decompose under nitrogen between 300 and 400 °C. Zn[Pd(HL)2] · 6H2O forms polymeric chains in the solid state, and the Zn2[M(L)2] · 14H2O (M = Ni, Pd) exhibit two-dimensional polymeric structures, each being isotypic with the respective Zn/Pt analogs. While the carboxylate groups in all these products are coordinated to zinc in a κO-monodentate mode, a structural variant of Zn2[Ni(L)2] having κO:κO′-briding carboxylate groups was also obtained. Exchange of the metal sites in the two Ni/Zn compounds was not observed, and these compounds are therefore diamagnetic.

Résumé :
An unusual heterobimetallic volatile compound [Pb2Co5(acac)14] was synthesized by the gas phase/solid-state technique. The preparation can be readily scaled up using the solution approach. X-ray powder diffraction, ICP-OES analysis, and DART mass spectrometry were engaged to confirm the composition and purity of heterobimetallic complex. The composition is unique among the large family of lead(tin): transition metal = 2:1, 1:1, and 1:2 β-diketonates compounds that are mostly represented by coordination polymers. The molecular structure of the complex was elucidated by synchrotron single crystal X-ray diffraction to reveal the unique heptanuclear moiety {Co(acac)2[Pb(acac)2-Co(acac)2-Co(acac)2]2} built upon bridging interactions of acetylacetonate oxygens to neighboring metal centers that bring their coordination numbers to six. The appearance of unique heptanuclear assembly can be attributed to the fact that the [Co(acac)2] units feature both cis- and trans-bis-bridging modes, making the polynuclear moiety rather flexible. This type of octahedral coordination is relatively unique among known lead(tin)-3d transition metal β-diketonates. Due to the high-volatility, [Pb2Co5(acac)14] can be potentially applied as a MOCVD precursor for the low-temperature preparation of lead-containing functional materials.

Résumé :
In the present research, a sonochemical approach was applied to prepare new cadmium(II) coordination 2D polymer, [Cd(L)(NO2)2]n (L = 1,2-bis(1-(pyridin-3-yl)ethylidene)hydrazine) and structurally characterized with various spectroscopic techniques including XRD, elemental analysis, SEM, and IR spectroscopy. The coordination number of cadmium (II) ions is seven (CdN2O5) by two nitrogen atoms from two organic Schiff base ligand and five oxygen of nitrite anions. The 2D sheet structures ended by nitrite anions and the nitrite anion displayed the end-stop role. The comprehensive system showed a three-dimensional structure with several weak interactions. The high-intensity ultrasound is regarded as an easy, environmentally-friendly, and flexible synthetic instrument for the compounds of coordination. CdO NPs was obtained by thermolysing 1 at 180 °C with oleic acid (as a surfactant). Further, the size and morphology of the produced CdO nanoparticles were investigated through SEM.

Résumé :
The development of straightforward reproducible methods for the preparation of new photoluminescent coordination polymers (CPs) is an important goal in luminescence and chemical sensing fields. Isophthalic acid derivatives have been reported for a wide range of applications, and in addition to their relatively low cost, have encouraged its use in the preparation of novel lanthanide-based coordination polymers (LnCPs). Considering that the photoluminescent properties of these CPs are highly dependent on the existence of water molecules in the crystal structure, our research efforts are now focused on the preparation of CP with the lowest water content possible, while considering a green chemistry approach. One- and two-dimensional (1D and 2D) LnCPs were prepared from 5-aminoisophthalic acid and Sm3+/Tb3+ using hydrothermal and/or microwave-assisted synthesis. The unprecedented LnCPs were characterized by single-crystal X-ray diffraction (SCRXD), powder X-ray diffraction (PXRD), Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM), and their photoluminescence (PL) properties were studied in the solid state, at room temperature, using the CPs as powders and encapsulated in poly(methyl methacrylate (PMMA) films, envisaging the potential preparation of devices for sensing. The materials revealed interesting PL properties that depend on the dimensionality, metal ion, co-ligand used and water content.

Résumé :
This study investigates the metallosupramolecular chemistry of functionalised 1,2-diazole ligands, by the preparation and characterisation of a range of first-row transition metal coordination polymers and discrete assemblies. To this end, twenty-six ligands containing 1,2-diazole functionality have been synthesised, twenty-one of which have not previously appeared in the coordination chemistry literature. Utilising these compounds, forty new coordination compounds have been prepared and characterised by single-crystal X-ray crystallography and other analytical techniques, and their solid-state structural features discussed in the search for reproducible new diazole-based synthons for the designed synthesis of new functional materials. Particular attention is paid to the contribution of the second nitrogen atom on the diazole ring, which participates in structure-directing hydrogen bonding interactions, or acts as a synthetic handle to easily append further functionality to the ligand system. The design of the ligands is separated into two primary categories, representing the different approaches adopted for the synthesis of the metallosupramolecular architectures. The combination of 1H-pyrazole and carboxylic acid functionality in mixed-ligand assemblies was investigated with the combination of bis-pyrazole and bis-carboxylic acid ligands, and with the preparation of ligands containing both functional groups. This approach was extended to the related heterocyclic species indazole, with all five possible isomers of indazole-carboxylic acid synthesised and used in coordination chemistry for the first time. The 1H-diazole-carboxylate synthon was employed in the synthesis of fourteen coordination polymers and three discrete assemblies. Heteroaryl substitution at the 1-position of pyrazole or indazole compounds was employed to generate chelating ligands containing pyridine or benzimidazole functionality, which were used to form nineteen discrete complexes, including dinuclear helicates and metallocycles, and five coordination polymers. The effect of flexibility and distance between coordination sites in bis-bidentate ligand systems was examined, in conjunction with studies into the effect of steric bulk and variation of the electronic nature of the coordinating groups. While this study is primarily concerned with the solid-state structural chemistry of 1,2-diazole coordination compounds, attention is paid where appropriate to solution-based measurements such as NMR and UV/Visible studies, and the pertinent behaviour of functional materials, such as thermogravimetric analysis for solvated species and gas uptake studies for stable void-containing materials.

Résumé :
Uranyl hybrid materials attract interest owing to promise of synthesizing functional materials, but typically experience limitations in extending dimensionality. This is due to the tendency of the uranyl cation to oligomerize along its equatorial plane, leading to the formation of flat secondary building units. One way to overcome these limitations is to utilize weak interactions to hold a structure together. This can be achieved through using ligands to build secondary building units through strong coordinative bonds that simultaneously provide supramolecular interactions as a means to extend dimensionality in the structure. We examined amino acids as a ligand choice because of its dual features of having a carboxyl group for coordination to the uranyl cation and an amino group that can be protonated to provide charge-assisted hydrogen bonding between to secondary building units in the structure. Aqueous benchtop chemistry in ambient conditions were used to synthesize and crystallize thirteen uranyl-glycine coordination compounds whose structures were elucidated with single crystal X-ray diffraction. Under these conditions, 1D coordination polymers form. The structural features in these compounds were varied to investigate their effects on the hydrogen bonding, including the presence/absence of metal center hydrolysis, the presence of other H-bond accepting carboxylate ligands, the use of dicarboxylic acid ligands to connect uranyl centers, and the addition of a secondary metal. The compounds provide insight into how the charge-assisted hydrogen bonding provided by zwitterionic amino acids is a viable means to extending the dimensionality of uranyl hybrid materials in a variety of chemical systems.

Résumé :
Liquid crystal polymers (LCP’s) comprise a class of melt-processable materials that derive specialized mechanical, chemical, and electrical properties from long-range molecular ordering. This unique microstructure gives rise to anisotropic bulk behavior that can be problematic for industrial applications, and thus the ability to model the orientation state in the polymer is necessary for the design of isotropic material manufacturing processes. Previous efforts to model LCP directionality have been primarily restricted to structured grids and simple geometries that demonstrate the underlying theory, but fall short of simulating realistic manufacturing geometries. In this investigation, a practical methodology is proposed to simulate the director field in full-scale melt-processing set-ups, specifically cast film extrusion, to predict the bulk material orientation state. The hybrid approach utilizes separate simulations for the polymer flow with commercial computational fluid dynamics (CFD) software, and the material directionality through a user-defined post-processing script. Wide-angle x-ray scattering (WAXS) is used to experimentally validate the simulated directionality during extrusion processing. It is shown that the model is capable of predicting both the direction and degree of orientation in the polymer resulting from processing, and the model produces strong agreement with experimental measurement of the polymer orientation state.
