Abstract
Twelve mixed ligand Co(II), Ni(II), Cu(II) and Cd(II) complexes involving both thiosalicylic and amino acids have been prepared and characterized by elemental analysis, molar conductivity, electronic and it spectral measurements. It is found that the monovalent amino- and salicylic acid are coordinated to the metal ions as NO and OS bidentate ligands where five and six membered chelate rings are formed. The ternary complexes formed are found to have a distorted octahedral geometry.
