A good precursor is foremost in the preparation of nanosized metal, metal oxide and mixed metal oxides. In the present study, a novel precursor nickel cobalt phenylacetate hydrazinate has been prepared which decomposes at 400oC to give the corresponding nanosized mixed-metal oxide. The synthesized complex has been characterized by elemental analysis and spectroscopic techniques. The thermal behaviour of the complex has been studied by thermogravimetry and differential thermal analysis. The Infrared analysis of the residue shows two absorption bands in the region 660-665 and 555-562 cm-1corresponding to the metal-oxygen stretching from tetrahedral and octahedral sites respectively, which are characteristics of cobaltites. Formation of cobaltite has been confirmed by thermogravimetry (TG) weight loss and X-ray diffraction. Combustion of the precursor in air yields fine powder of cobaltites with large surface area which has been confirmed by XRD patterns.
