Abstract: The mixed ligand complexes [Cr(A)2(nic)2] 2 {Hnic = nicotinic acid, HA = glycine (Hgly), phenylalanine (Hpala) or -methionine (Hmet)} and K[Cr(glutu) (A)(H2O)} {glutn = glutathione; HA=alanine (Hala), Hmet or histidine (Hhis)} have been synthesised and characterized. A facial octahedral geometry is suggested for the complexes on the basis of electronic spectral studies. IR spectral studies indicate that bonding with chromium atom occurs through the amino and carboxylate groups of the amino acids, bridging carboxylate group of Hnic, and amino, thiol and amide groups of glutn. Results of the thermal decomposition studies are also discussed.
