Synthesis and spectral characterization of zinc(II) and cadmium(II) complexes of acetone- N(4)-phenylsemicarbazone: Crystal structures of acetone- N(4)-phenylsemicarbazone and a cadmium(II) complex

Abstract

Seven Zn(II) and Cd(II) complexes of ON donor acetone- N(4)-phenylsemicarbazone (HL) have been synthesized and physico-chemically characterized by partial elemental analyses, molar conductance measurements, infrared, electronic and 1H NMR spectral studies. The semicarbazone binds the metal as a neutral bidentate ligand in all the complexes. The crystal structures of acetone- N(4)-phenylsemicarbazone and [Cd(HL) 2Cl 2] have been determined by X-ray diffraction studies. The coordination geometry around cadmium(II) in the complex [Cd(HL) 2Cl 2] is distorted octahedral.
