102Abstract In this project the synthesis and characterization of the complexes with possible bio andelectro or photochemical applications have been discussed 1 Co bnzacdien bzlan ClO4 2 Co bnzacdien mrpln BPh4 3 Co bnzacdien prldn BPh4 4 Co bnzacdien pprdn BPh4 5 Co bnzacdien py BPh4 6 Co bnzacdien 3 Mepy BPh4 7 Co bnzacdien 4 Mepy BPh4 8 Co bnzacdien N MeIm BPh4The complexes 1 to 8 are synthesized in good yield and are characterized by FT IR UV Vis and 1H NMR spectroscopy and elemental analyses The structure of complex 1 havebeen determined by X ray crystallography and the correlation between structural andspectroscopic properties are discussed It seems that the pentadentate ligand is coordinatedunsymmetrically to the cobalt centre Therefore the methyl groups on the imine carbon of thepentadentate ligand appear as tow separate singlets in the 1H NMR spectrum The steric effects on the structural properties of these complexes are discussed and comparedwith those of similar complexes that have been reported The electrochemical properties of complexes 1 2 5 7 are also studied by CyclicVoltammetery The results show that the reduction of Co III to Co II is irreversible and thereis no direct correlation between the redox potentials and the pKa of axial amines and thesepotentials are dependent on structural effects
