Synthesis and characterization of mixed ligand complexes of Cu(II), Ni(II) and Co(II) with cytidine and amino acids

Abstract

The mixed ligand complexes of Cu(II), Ni(II) and Co(II) with cytidine and amino acids, L-alanine, L-phenylalanine and L-tryptophan have been synthesized and characterized by elemental analysis, conductivity, Infrared spectra, electronic spectral data and magnetic susceptibility measurements. In these complexes, the nucleoside acts as a monodentate ligand involving only N(3) in metal coordination whereas the amino acids acts as bidentate ligands coordinating through carboxylate oxygen and amino nitrogen. A distorted octahedral geometry for Cu(II), and octahedral geometries for both Ni(II) and Co(II) was proposed.
