Studies on bis(Hydrazine) Metal Malonates and Succinates

Abstract
Several new bis(hydrazine) complexes of metal malonates and succinates of the formula MX(N2H4)2 (M = Co, Ni, Zn and Cd; X = malonate or succinate) have been prepared and characterized by chemical analyses and magnetic and spectral studies. The magnetic moments and electronic spectra indicate that these complexes are of high spin octahedral variety Infrared spectra show the bidentate nature of both the hydrazine and malonate/succinate moities The thermal degradation (TG and DTA) of the compounds yield metal oxides as the final residue. X-ray powder diffraction patterns show that each series of compounds are isomorphous among themselves.
