Synthesis and Characterization of Mixed Ligands Complexes of Copper(II) Ion with Nitrilotriacetic Acid and Amino Acids

Abstract

The mixed ligand complexes of copper (II) ion with nitrilotriacetic acid and amino acids (alaine, glycine, lysine and histidine) were synthesized and characterized by IR and UV-vis spectroscopy. The IR spectra of complexes display the typical absorption bands of nitrilotriacetic acid and amino acid ligands. Electronic spectra data for the complexes were in accordance with distorted octahedral environment around the central Cu(II) ion. The amino acids groups act as bidentate chelating ligand.
