Abstract:
Tetradentate acyclic compartmental Schiff base ligand with N2O2 compartment afford suitable coordination environment for large variety of metal ions. This type of ligands can easily be synthesized by [2+1] condensation of a carbonyl compounds with a diamine. Several metal complexes have been reported from the single- and double-compartment acyclic Schiff base ligands which are the [2+1] condensation products of salicylaldehyde, 2-hydroxyacetophenone, 3-methoxysalicylaldehyde, 3-ethoxysalicylaldehyde and a diamine; The diamine counterpart in these ligands are ethylenediamine, 1,3-diaminopropane, 1,4-diaminobutane, 1-methylethylenediamine, 2,2-dimethyl,1,3-diaminopropane, o-phenylenediamine, trans-1,2-diaminocyclohexane, etc. Several review article has been published previously on compartmental Schiff base ligand compounds. This review article focused only the type and structures of Cu(II)/Ni(II)-second metal (s-, p-, d10-, 3d-,, 4f- block metal) homo-/hetero- nuclear coordination comppounds derived from single compartmentl salicyaldehyde-diamine and acetophenone-diamine ligand systems.

Abstract:
Choice of ligands is significant to successful synthesis of metal complexes (coordination compounds). This study reports the use of Schiff base as the right ligand to control the poor bioavailability and neurodegenerative toxicity challenges of manganese ion. In line with this study, document analysis was used as the methodological approach to evaluate the significance of Schiff base ligands in easing these manganese’s challenges and aligning the resultant coordination compounds (manganese Schiff base complexes) as therapeutic agents in anticancer studies. Report also involves crystallographic studies where single crystal X-ray crystallography was used as a chemical characterization technique. In addition, molecular docking studies, MOE2008, and AutoDock software were used to reveal the mode of interaction between the Schiff base and the manganese(II) and (III) ions, as well as scrutinizing the biological efficacy of the manganese(II) and manganese(III) Schiff bases coordination compounds as anticancer agents against some anticancer cell lines. Conclusion drawn was that manganese(II) and manganese(III) Schiff bases coordination compounds gave more active and potent activities than the corresponding Schiff bases. As a result, challenges of neurodegenerative toxicity and poor bioavailability of manganese ion were overcome, and the chelation therapy was fulfilled. Results from single crystal X-ray crystallography confirmed the successful synthesis of manganese(II) and manganese(III) Schiff bases coordination compounds and revealed the mechanism of reaction, while the molecular docking buttressed the biological activities of the Schiff base ligand and manganese Schiff base coordination compounds by portraying the structure activity relationship (SAR) between either Schiff base or the manganese Schiff base coordination compounds and the virtual cancer cell line (receptor protein), where hits were obtained for lead optimizations.

Abstract:
Schiff Base are organic ligand that contained azomethine linkage (-HC=N-) which shows biological importance. Schiff Base from vanillin and 2-aminophenol was synthesized in 1:1 mole ratio. The complexes of Cr (II) and Co (II) from Schiff Base in 1:2 mole ratio metal-ligand (M-L) and the mixed ligand complexes from Schiff Base and 2-aminophenol in 1:1:1 mole ratio ligand-metal-ligand(L-M-L) were synthesized and characterized based on solubility, melting point, conductivity, Fourier transform infrared spectroscopy (FTIR) and ultraviolet (UV). The solubility result shows that, dimethyl sulfoxide(DMSO) dissolved all the complexes. The results obtained from melting point, conductivity indicated purity and non-electrolytic of the complexes respectively. In metal complexes, the infrared data showed the ligands is coordinated to the metal ion through azomethine nitrogen, oxygen in methoxyl group and oxygen in phenolic group. In mixed ligand complexes, the infrared data revealed the ligands is coordinated to the metal ion through azomethine nitrogen, oxygen in methoxyl group, oxygen in phenolic group and nitrogen in amino group. The results showed a six coordinate octahedral geometry for these complexes. The ligands and the metal complexes were examined for their antibacterial activity using agar well diffusion method against Escherichia coli, Staphylococcus aureus, streptococcus pyrogens , Klebsiella pneumonia (gram - bacteria), and Bacillus sutilis, Staphylococcus aureus (gram + bacteria). In comparing the results, the complex of Co(HL1)2 has greater zone of inhibition against the tested organism than the free ligands as antibacterial agent.

Abstract:
Schiff bases have been synthesized by the reaction of triazole containing primary amine with aromatic carbonyl compounds. The Schiff bases prepared, act as ligand when these are made in contact with oxovanadium (VO2+) ion. Some new mononuclear oxovanadium(IV) complexes have been synthesized by the reaction of Schiff base ligands with vanadyl sulphate (VOSO4.xH2O) and the complexes are analyzed by different spectroscopic methods; [fourier-transform infrared (FTIR), ultraviolet-visible (UV-Vis.), electron paramagnetic resonance (EPR)], X-ray diffraction (XRD) analysis, elemental analysis, and conductivity measurement. The complexes have been well characterized based on analytical data. The electrolytic nature of the complexes was determined based on the molar conductance values. The powder XRD pattern has been used to determine crystal size and type. The synthesized Schiff base ligands and oxovanadium(IV) complexes were found to be stable in air and moisture at room temperature. On the basis of the physicochemical data, the tentative geometry of the complexes has been proposed. Antibacterial sensitivity of the ligand and its metal complexes have been assayed in vitro against bacterial pathogens viz. growth inhibitory activity of ligands and complexes against pathogens has also been determined.

Abstract:
Because of their importance in a variety of interdisciplinary study domains, Schiff-base ligands have performed a significant role in the evolution of contemporary coordination chemistry. This almost-comprehensive review covers all the aspects and properties of complexes, starting from the Schiff-base ligands. Our work is centered on the eloquent advances that have been developed since 2015, with special consideration to recent developments. Schiff-base ligands and their complexes are adaptable compounds obtained from the condensation of two compounds: a carbonyl with an amino. The correspondent metal complexes have been shown to have antifungal, antibacterial, antioxidant, antiproliferative, and antiviral properties. This review begins with a short introduction to Schiff-base ligands and their metal complexes. It stands out in the recent advancements in the Schiff-base coordination chemistry domain and its future prospects as a potential bioactive core. Additionally, the review contains knowledge about the antioxidant, redox, and catalytic activities of the Schiff-base complexes, with important future applications in the obtaining of new compounds and materials.

Abstract:
Four dioxidovanadium(V) complexes with Schiff-base ligands based on 2-hydroxybenzhydrazide with four different substituted salicylaldehydes (5-chlorosalicylaldehyde, 3,5-dichlorosalicylaldehyde, 5-nitrosalicylaldehyde, 3-bromo-5-chlorosalicylaldehyde) were synthesized and described, by using V2O5 and triethylamine. The single crystal X-ray structure measurements as well as elemental analyses and IR spectra confirmed the formulas of the ionic complexes with a protonated triethylamine acting as counterion, HTEA[VO2(L)] (HL = Schiff-base ligand). The kinetic stability of the complexes at pH = 2 and 7 was discussed with respect to the neutral vanadium(V) complexes previously studied as potential insulin-mimetic agents. A correlation between the substituents in an aromatic ring of the Schiff-base ligands with crystal packing, and also with the stability of the compounds, was presented.

Abstract:
In the present paper, synthesis of Schiff base ligands and the metal complexes are studied and compared by conventional and solvent free route. The synthesis of Schiff base ligands of amino acids (Glycine, Phenylalanine and Tyrosine) with salicylaldehyde and their mixed ligand ternary Cu(II) complexes are discussed. Other ligands are used in co-ordinaion with the schiff base is 1,10- Phenanthroline/thiourea in equimolar ratio. The environmentally efficient and modern developed method for synthesis is the solid state synthesis of salicylidene amino acids through pestle mortar synthetic procedure. This method is compared with the conventional method that require refluxing the reactant mixture for hours in an organic solvent, here ethanol. The complexes are characterized by spectral techniques IR spectroscopy and UV spectroscopy. The investigations concluded that the pestle mortar assisted method is very rapid , simple and economic for the preparation of ligands and complexes as well. The Antimicrobial studies were also performed for the complexes. The spectral data for the ligands and complexes obtained from either method, conventional and solventless procedure are in good agreement with one another. The azomethine bonding(-CH=N-) between salicylaldehyde amino acids based Schiff bases is described by the IR spectral peak around 1600 cm-1.

Abstract:
The synthesis, characterization and antimicrobial activity determination of some aminopyridine- and (aminomethyl)pyridine?salicylaldimine copper(II) complexes were realized. The ligands, L1?L6, were prepared by condensing salicylaldehyde and o-vanillin with 2- and 3-amino- and (aminomethyl)pyridine, respectively. The complexes were characterized by micro-analytical, electronic, infrared and conductivity data. The structures of the Schiff base ligands were further confirmed from 1H- and 13C-NMR spectral data. This study established that salicylaldimine ligands could coordinate as neutral species via the imine-N and the undeprotonated phenolic-O. The complexes have the molecular formula: [CuLCl], [Cu(LH)2Cl2]?xH2O or [Cu(LH)Cl(H2O)]Cl. The X-ray crystal structure of [CuL6Cl] indicated a square planar geometry with the Schiff base ligand coordinated to the Cu(II) ion as a tridentate monobasic, N2O, ligand. The crystals crystallized in a monoclinic system with P21/c space group. All the ligands and their Cu(II) complexes were screened for their antimicrobial activity against Staphylococcus aureus subsp. aureus ATCC? 6538?*, Bacillus subtillis subsp. spizizenii ATCC? 6633?*, Escherichia coli ATCC? 8739?* and Candida albicans ATCC? 2091?* using agar diffusion and broth dilution techniques. The presence of the methoxyl group enhanced the antimicrobial activity of the salicylaldimine Schiff base ligands.

Abstract:
Dinuclear complexes have been studied for different purposes: magnetic materials[1], Non-linear optics materials[2], molecular switches [3], mixed-valence systems, etc. With these antecedents in mind, we present in this work a new series of dinuclear Iron(III) complexes formed by different Schiff bases ligands. The reaction starting from the iron chloride salts with the 5-chloro or 5-bromo-salycilaldehyde and ethylendiamine yields two different kinds of dinuclear iron complexes in different reaction conditions. The first one (Fig N°1), are methoxo-bridged dinuclear iron(III) complexes in which each metal centre is coordinated with one mono-condensated Schiff base ligand, one 4-chloro or 4-bromo-2-(dimethoxymethyl)phenoxo ligand and two bridging methoxo ligands. The iron(III) centres are hexacoordinated (FeN2O4), the coordination sphere is formed by 2 nitrogen atoms of the ethylendiamine fragment, 2 oxygen atoms from the hydroxyl of the Schiff base and two O atoms from the methoxo ligands. Both iron(III) centres are related by a inversion centre. The second one (Fig N°2), the dinuclear complex is formed for the double condensation of ethylendiamine with 5-chloro or 5-bromo-salycilaldehyde and one oxygen from the dianionic ligand act as bridge with another unit. The iron (III) centres are also hexaccordinated (FeN2O3Cl) formed by 2 nitrogen atoms from ethylendiamine fragment and 3 oxygen atoms from hydroxyl from Schiff base ligands and one chloro ligand. Finally, the electronic and redox properties have been studied by UV-Visible and cyclic voltammetry. ACKNOWLEDGMENT FONDECYT N01130640, FONDEQUIP EQM120095 and Beca CONICYT folio 21130944

Abstract:
The synthesis, structures and physical properties of tripodal and macrocyclic Schiff base ligands and their complexes are described. All ligands are synthesised by the condensation of amines with 2,6-diformyl- or 2,6-diacetyl-phenols. The synthesis of a novel dodecadentate tripodal Schiff base ligand, L1H3, is described. Reaction of L1H3 with Ln(ClO4)3 where Ln=La, Pr gives complexes of the form [Ln(L1H3)(H2O)](CIO4)3 and where Ln=Y, [Y(L1H3)](CIO4)3. The single crystal X-ray structures of L1H3 and complexes are described. L1H3 reacts with Gd(CIO4)3 in the presence of Cu(CIO4)2 and N,N-diisopropyl-ethylamine resulting in hydrolysis of the acetal functionality to give a complex of the nonadentate tripodal ligand L5H3, [Gd(L5H3)(H2O)2](CIO4)3, the single crystal X-ray structure of which is described. A similar reaction occurs with Ni(CIO4)2, giving [Ni(L5H3)](CIO4)2, The X-ray structure of which is also described. The preparation of L-H3, a related tripodal nonadentate ligand, is described and the structure determined by single crystal X-ray analysis. Complexes prepared by reaction with M(CIO4)2, M=Ni, Zn, are of the form [M(L2H3)](CIO4)2 and the single crystal X-ray structures show the two complexes are isostructural. The Schiff base macrocycle [L3H4](PF6)2 reacts to form [Cu2L3(CH3CO2)]Br preferentially in the presence of La(CIO4)3 and Cu(CH3CO2)2. The single crystal X-ray structure is described. A template condensation of 2,6-diformyl-4-methylphenol and tris(2-amino-ethyl)amine around yttrium(III) yields a complex of the macrobicyclic ligand. L6H3, [Y(L6H3)(H2O)2](CIO4)3, the single crystal X-ray structure of which is described. [La(L6H3)(H2O)](CIO4)3 was further reacted with Ni(CIO4)2 in the presence of N,N-diisopropylethylamine to form the heterobimetallic complex [LaNi(L1)(H2O)](CIO4)2, the structure of which was confirmed by single crystal X-ray analysis. Preliminary magnetic studies on the complex [GdNi(L1)](CIO4)2 indicate a weak ferromagnetic coupling between the metals.

Abstract:
Il y a de nos jours un besoin urgent de découvrir de nouveaux médicaments pour relever le défi de la multirésistance dans le traitement des infections bactériennes et le cancer. Dans cette perspective, des bases de Schiff dérivées de dithiocarbazates et leurs complexes métalliques correspondants sont des candidats intéressants puisqu'ils peuvent être facilement synthétisés et permettent une grande diversité de coordination. Dans cette étude, des complexes tetradentes et bidente ont été préparés. Les ligands et complexes synthétisés ont été entièrement caractérisés par différentes méthodes spectroscopiques et physico-chimiques dans le solide et en solution. L'activité antibactérienne de ces complexes a ensuite été étudiée et a permis de sélectionner un complexe " leader " (plus efficace, stable et fonctionnalisable). Ce complexe a alors été modifié afin d'augmenter sa stabilité en milieux biologique, sa solubilité dans l'eau ainsi que son activité. Il a été conjugué avec différentes entités : des peptides pénétrants, un polyéthylène glycol (PEG) et un peptide inhibiteur des pompes d'efflux bactériennes. Ces complexes ont montré une remarquable activité antibactérienne sur neuf souches de bactéries Gram-positives et Gram-négatives et en particulier, ils se sont avérés très efficaces contre S.aureus. L'activité anti-cancéreuse des complexes non-conjugués a également été étudiée et les complexes de cuivre sélectionnés et testés sur des cellules de cancer du sein ont montré une cytotoxicité élevée. Ceci met en évidence la pertinence d'utiliser les complexes métalliques, pour à la fois stabiliser les ligands et générer des composés plus actifs
There is an urgent need to discover new drugs with novel mechanisms of action, higher activity and improved selectivity to address the severe challenge of multidrug resistance in treating bacterial infections and cancer. In view of this, Schiff bases derived from S-substituted dithiocarbazate and their corresponding metal complexes with a plethora of potentially exciting biological activities and coordination chemistry are attractive candidates. Metal complexes of tetradentate NNSS and bidentate NS ligands have been prepared. The compounds were fully characterized with various physico-chemical and spectroscopic methods in solution and solid state. Conjugation of the most promising antimicrobial compound to various moities (polyarginine, polyethylene glycol (PEG) and an bacterial efflux pump inhibitor) was achieved to prepare improved therapeutic agents. The nanoarginines (R9) derivatives showed the most encouraging synergistic effect upon conjugation and complexation to copper ion with enhanced water solubility, bacteria cell membrane permeability and bioactivity. The Cu(II) R9 derivatives possess remarkable antibacterial activity against a wide spectrum of bacteria and in particular, highly efficacious against S. aureus. This show that the conjugation of polyarginine to dithiocarbazate compounds can greatly influence their therapeutic potential. Cytotoxic assay was also carried out for selected non-conjugated compounds. All the selected Cu(II) complexes assayed against breast cancer cells lines exhibited good cytotoxicity. This work highlights the relevance of the strategy that consists of using metal complexes to stabilize the ligands and improve their bioactivity

Les travaux realises au cours de cette these ont pour but de modeliser le centre actif de la metalloproteine a manganese du photosysteme ii vegetal. Pour ce faire, nous avons prepare et etudie deux familles de complexes incorporant des bases de schiff pentadentees a sites donneurs n#2o#3 comme ligands binucleants. Parmi les dix neuf complexes prepares, nous avons determine la structure moleculaire d'un complexe dinucleaire du mn(iii), de trois complexes tetranucleaires mn(ii)#2mn(iii)#2 et d'un complexe tetranucleaire mn(iii)#4, par diffraction des rx. Dans la premiere partie de notre travail, les ligands de type 1,3-bis(z-salicylideneamino)propane-2-ol ont conduit a six nouveaux complexes polynucleaires du mn(ii) et trois nouveaux complexes du mn(iii) dont deux sont binucleaires. La deuxieme partie concerne l'etude des complexes du manganese avec les ligands de type 1,5-bis(z-salicylideneamino)pentane-3-ol. En milieu rigoureusement anaerobe, les complexes precurseurs de cette deuxieme serie, mn#i#i#2(l#2)(-oac)#n, reagissent avec le methanol pour conduire a des especes tetranucleaires a valence mixte mn(ii)#2mn(iii)#2 et, pour certains, avec l'eau de melanges methanol/eau ou ethanol/eau pour conduire a des especes tetranucleaires mn(iii)#4. Au cours de ces reactions les deux anions methanolate ou oxo formes sont stabilises sous forme de ligands -3 pontants. Les etudes electrochimiques mettent en evidence l'accessibilite de six etats d'oxydation allant de mn(ii)#4 a mn(iii)#2mn(iv)#2. Associees a la caracterisation des especes bisdinucleaires a valence mixte, elles suggerent que la deuxieme reaction fait intervenir deux etapes successives a deux electrons.

Abstract:
This work investigated the use of large tetradentate mixed nitrogen and oxygen donor macrocycles as potential ligands for titanium(IV).These large ligands are capable of encapsulating the metal ion, thereby protecting it from reacting further. In addition, titanium complexes of this type had not been reported previously.Molecular modelling was utilised to evaluate and predict the coordinating potential of the macrocycles investigated.An alternative synthetic strategy was needed to achieve coordination complexes with titanium. This involved the use of a benzene based solvent system and rigorously dry reaction conditions.The final part of the work involved a detailed study of the kinetics of the hydrolysis of the titanium complexes investigated.
