A series of Co(II) complexes with new Schiff bases ligand and various amino acids in aqueous methanol solution have been synthesized. The synthesized Schiff bases and their Co(II) complexes have been characterized by various sophisticated analytical instruments for their magnetic susceptibility, thermal, spectral and electrochemical analysis These ligands act as tetradentate species with N and O as donor atoms and facilitate the metal to center . The plausible octahedral structures have been alloted to these complexes. A typical cyclic voltammogram obtained in the potential range of -1.6 V to +1.6 V (Ag│AgCl) on GCE for [Co2(CMAIPA)(H2O)4] using in TEAP an irreversible oxidation peak at ~ 0.850 V and another quasi reversible reduction peak at ~-1.250 V are observed.
