Synthesis and Charac terization of New Complexes of (N-4-Methoxy Phenyl) Amino Phenyl Acetonitrile Ligand with Some Divalent Transition Metal Ions

Abstract

The synthesis and characterization of new complexes of Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) with bidentate (N-4-methoxy phenyl) amino phenyl acetonitrile ligand which was prepared from benzaldehyde and 4-methoxy aniline in the presence of KCN and acidic medium have been described. The complexes were synthesized by treating an ethanolic solution of the ligand with appropriate amount of metal salts [1:2] [M:L] ratio. The complexes were characterized by metal and elemental analysis, infrared and electronic spectra, molar conductivity, magnetic susceptibility, and mole ratio method. According to obtained data the probable coordination geometries of Manganese, Cobalt, Nickel, Copper, and Zinc in these complexes with N2-donor of ligand atoms are octahedral. All complexes were found to be non-electrolyte in absolute ethanol, and the complexes were formulated as [ML2Cl2].XH2O.

Keywords: α-aminonitrile, Manganese, Cobalt, Nickel, Copper and Zinc Complexes.
