The deprotonated amide is a strong ?-donor capable of stabilizing early as well as late metal ions in high oxidation states, making high-valent metal complexes of the ligands suitable as Lewis acid catalysts. Of special catalytic interest are Mn and Mo-calalyzed allylic alkylations. Since the pyridine nitrogen resembles the imidazole nitrogen, metal complexes of bispyridylamides have been employed as models for metalloenzymes. In addition, the coordination chemistry of bispyridylamides, have found use in dendrimer synthesis, molecular receptors and platinum(II) complexes with antitumour properties. In this thesis [Co(Me)(Amine) 2 ]X complexes, which have biochemical and photochemical properties, with these formula (1) [Co(Me)(N-MeIm) 2 ]B(Ph) 4 , (2) [Co(Me)(3-MePy) 2 ]ClO 4 , (3) [Co(Me)(3-AcPy) 2 ]ClO 4 , (4) [Co(Me)(Prldn) 2 ]ClO 4 , (5) [Co(Me)(Pprdn) 2 ]ClO 4 , (6) [Co(Me)(Mrpln) 2 ]ClO 4 , (7) [Co(Me)(Bzlan) 2 ]ClO 4 were synthesized. Methyl group induces a higher ?-donating power to the equatorial ligand which in turn stimulates the bond formation between Co(III) and ?-acceptor amines. We succeeded to synthesize complexes with ?-acceptor axial ligands, that could not be synthesized with ligand. These complexes were characterized by UV-Vis, FT-IR, 1 HNMR and Elemental Analysis. Complex (4) was structurally characterized by X-Ray Diffraction. Some electrochemically properties of complexes 1-7 were also investigated by Cyclic Voltammetry, and the trend in the observed redox potential was rationalized considering the axial ligand properties.
