Abstract

Metal-hydrazine complexes, $[M(N_2,H_4)_n]^{2+}$ (M = Mn, Fe, Co, Ni, Zn and Cd, n = 2 or 3) with different anions like sulphate, sulphlte, acetate, formate, oxalate, hydrazinocarboxylate, nitrate and perchlorate have been investigated as precursors to oxide materials. The thermal reactivity of these complexes changes dramatically with the anion, e.g. sulphate, sulphite, acetate and formate complexes - decompose; oxaiate and hydrazinocarboxylates -deflagerate and nitrate and perchlorate complexes-detonate. The defiagerating nature of the metal-hydrazine oxalates and hydrazinocarboxylates has been employed in the combustion synthesis of fine particle $ y- Fe_2O_3, Fe_3O_4$, ferrites and cobaltites at low temperature.
