Metal complexes of the essential amino acids(leucine, methionine) [M(L.H2O)2], where L (leucine, methionine), [M:Co+2,Ni+2,Cu+2,Zn+2,Cd+2], have been prepared from the reaction of chloride- salt of transition metal. With sodium salt of the amino acid. The complexes have been characterized by means infrared spectra and atomic absorption analysis. The IR spectra and atomic absorption analysis show that amino acids actas bidentate ligands.IR spectroscopy confirms the ligand coordination to the metal ions through carboxyl and amine groups. The prepared complexes show poor solubility in water and in the common organic solvents.
