Bis-hydrazine metal o-nitrobenzoate, [M(o-NO2C6H4COO)2(N2H4)2], where M= Co, Ni, Zn or Cd have been prepared by mixing aqueous solution of respective metal nitrate hydrate with aqueous solution containing onitrobenzoic acid and hydrazine hydrate in 2:4 ratio. These complexes were analysed by chemical and CHN analyses. The IR spectrum of these complexes reveals the monodentate nature of carboxylate ions and bridged bidentate nature of hydrazine. Thermal behaviour of these complexes shows single step decomposition to give respective metal oxide as the final product except zinc complex which after dehydrazination in the first step undergo pyrolysis to give ZnO. X-ray powder patterns indicate that the complexes are isomorphism. The mixed metal complexes, [M1/3Co2/3(o-NO2C6H4COO)2(N2H4)2] have also been prepared using aqueous solution of mixture of metal ions in appropriate ratio. These precursors on thermal degradation yielded respective metal cobaltites as the end residue. The formations of these cobaltates were confirmed by chemical analysis, IR spectra and X-ray powder diffraction studies.
