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, L<SUP>1</SUP>H<SUB>3</SUB>, is described.

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 rigorous

Abstract:
Several Schiff base ligands, N, N‟-(aryl)benzyaldiimine ligands (R-BEN); N, N‟-(aryl)benzyaldiamine dihydrochloride ligands (R-BENH•2HCl); N, N‟-(aryl)benzyaldiamine ligands (R-BENH); N, N‟-bis(cinnamaldiimine) ligands (R-CA2EN) were synthesized for the investigation of the electronic effect of the substituents at para-position of the Schiff base ligands and their copper complexes. The synthesis of Schiff bases was carried out by reacting a series of para-substituted benzyaldehyde, and para-substituted cinnamaldehyde with ethylenediamine. The imine group of Schiff bases, N, N‟-(aryl)benzyaldii

Les annees 1980 ont ete marquees par l'apparition de nouveaux materiaux: les polymeres organiques conducteurs comme les polyanilines, les polypyrroles et les polythiophenes qui sont synthetises par oxydation electrochimique. Un nouveau developpement de ces materiaux est apparu avec l'idee d'introduire dans la matrice des especes possedant une activite electrochimique propre, comme des complexes de coordination. Ces materiaux dopes constituent les electrodes modifiees qui sont utilisees en electrocatalyse. Les complexes de coordination retenus pour cette etude sont essentiellement des complexes

Esta tese apresenta a síntese e a caracterização de novos complexos de rênio e tecnécio utilizando como agentes complexantes ligantes assimétricos do tipo base de Schiff e ligantes triaminas derivadas da dietilenotriamina. Os ligantes assimétricos foram sintetizados através de reações de condensação entre 2,2\'-dihidroxibenzofenona e as aminas alifáticas etilenodiamina e dietilenotriamina, formando, respectivamente, os ligantes 2,2\'-(((2-aminoetill)imino)metileno)difenol(HL1) e 2,2\'-(((2-((2-aminoetil)amino)etil)imino) metileno)difenol (HL2).

Abstract:
Nas últimas décadas, os complexos de metais de transição vêm sendo investigados devido as suas atividades antineoplásica e tripanossomicida. Há diversos trabalhos na literatura que buscam explorar as propriedades de complexos de paládio, entre elas podemos citar: avaliação de atividade como anti-proliferativo de células cancerosas, avaliação de atividade anti-inflamátoria, avaliação de atividade bactericida e aplicações em processos catalíticos. Nosso material de estudo foram compostos de paládio(II) contendo ligantes imínicos. Os Ligantes N,N’-bis(3,4-dimetoxibenzaldeído)etano-1,2-diamina (3,
