Abstract :

Copper α–amino acid complex attracts attention of chemists because of its different kind of biological applications. Amino acids having both, amine and carboxylic acid groups attached to the first, or alpha, carbon atom have particular importance in biochemistry. Complexes of copper(II) with amino acids can be used as models to study the pharmaco–dynamic effects of drugs or for increasing the biocompatibility and minimize toxic effects of some metal ions. Therefore, this attraction we were synthesized the new series of complexes of copper(II) with various amino acids namely L–threonine, L–tyrosine, L–tryptophane, L–histidine and characterized as mononuclear species on the basis of elemental chemical analysis, infrared spectra, UV–Visisble and cyclicvoltametery measurements. The IR spectra indicated the presence of amino acid coordinated through nitrogen atom and the oxygen from the carboxylic group. The experimental data suggest that the ligands act as bidentate and adopt an octahedral stereochemistry. This paper consist synthesis, elemental analysis and characterization of these complexes.
