The peptide group is an important construction unit in chemistry and biology and close resemblance of amide groups to peptide linkages in proteins have been aroused by inorganic chemists in their coordination chemistry. Consequently, a large variety of pyridine amide ligands have been synthesized for investigating their metal- binding properties, for providing models from the standpoint of bioinorganic chemistry, for use in catalysis and as molecular receptors. In addition, the coordination chemistry of bispyridylamides, have found use in dendrimer synthesis, molecular receptors, platinum(II) complexes with antitumour properties and stabilization of metal ions in high oxidation states. The amide hydrogen atoms become labile when the ligand undergoes complexation, which often resulted in the formation of a mono- or a dianionic ligand. Deprotonated amide groups have maximum electronic delocalization and strong ? donating properties. These groups usually coordinate via the nitrogen atom whereas coordination via oxygen is more frequent for neutral ligands. In this thesis the synthesis of the new ligand (H 2 c) and [Co(c)(Amine) 2 ]X complexes, which may have biochemical and photochemical applications (1) [Co(c)(N-MeIm) 2 ]PF 6 , (2) [Co(c)(py) 2 ]ClO 4 , (3) [Co(c)(3-Mepy) 2 ]PF 6 , (4) [Co(c)(4-Mepy) 2 ]PF 6 , (5) [Co(c)(prldn) 2 ]PF 6 , (6)[Co(c)(pprdn) 2 ]PF 6 , (7) [Co(c)(mrpln) 2 ]ClO 4 , (8) [Co(c)(bzlan) 2 ]PF 6 are reported. We succeeded to synthesize complexes with ?-acceptor axial ligands, that could not be synthesized with and bqb ligands. The chlorine group on the equatorial ligand induces a higher ?-donating ability to the equatorial ligand which in turn stimulates the bond formation between Co(III) and ?-acceptor amines. The H 2 c and its cobalt complexes were characterized by UV-Vis, FT-IR, 1 HNMR and Elemental Analysis. Complex (3) was structurally characterized by X-ray diffraction. Some electrochemically properties of complexes 1-8 were also investigated by cyclic voltammetry, and the trend in the observed redox potential was rationalized considering the axial ligand properties.
