Synthesis and spectral studies of new Co(II), Cu(II), and Ni(II) metal complexes with aromatic diamine

Abstract

1,2-bis(p-aminophenoxy)ethane was obtained with reduction of 1,2-bis(p-nitrophenoxy)ethane and Pd/C as catalyst in hydrazine hydrate. Co(II), Cu(II), and Ni(II) complexes of aromatic bidentate diamine were prepared. The structure of the ligand and its complexes were characterized by IR, elemental analysis, magnetic susceptibility, conductivimetry, UV-Vis and H-1 NMR spectroscopy. The metal/ligand mole ratios were found to be 1:1. The general compositions of these complexes are found to be [CoLCl2], [CuLCl2], and [CoLCl2].
