摘要：In this paper a new series of complexes of Co(II) and Ni(II) with amino acid and 2-amino-iso butyric acid have been synthesized exhibits 1:2 metal-ligand ratio. Characterization of the ligand as well as complexes has been done on the basis of elemental analysis, Infra-r ed and magnetic susceptibility measurements. The ligand have been found to Co-ordinate thr ough nitrogen and sulphur atoms. The complexes are binary and ternary complexes and are thermally stable. The present paper describe the formation of complexes of Co(II) and Ni(II) with L-cystein and 2-amino is butyric acid
