  • Abstract

    Five mixed-ligand complexes of copper(II) with 1, 10-phenanthroline and some selected aromatic ligands such as imidazole, 2-aminopyridine, 4- dimethylaminobenzonitrile, 2,2’dipyridylketone, 4-methylimidazole-5-carboxaldehyde have been synthesized and characterized by microanalyses, spectroscopic and room temperature magnetic susceptibility measurements. The microanalyses data is satisfactory with the formation of the prepared complexes. The infrared spectra of the complexes reveal the involvement of the donor groups of the selected aromatic compounds attached to the copper metal in the formation of the mixed-ligand complexes. The electronic spectra in the visible region show the high energy, high intensity peaks between 13,647 cm-1 and 15,322 cm-1. The mass spectra of the complexes are supportive of the microanalytical data.
