The thermal decomposition of [Ni(N<SUB>2</SUB>H<SUB>4</SUB>)<SUB>6</SUB>]X<SUB>2</SUB> (X=Cl, Br, I) in solid phase was investigated by means of derivatography and IR spectral measurement. It was found from the derivatography that the decomposition of the chloride and bromide proceeded <I>via</I> tris-, bis-, and mono-hydrazine complexes as metastable reaction intermediates, while tetra-hydrazine complex was produced in the decomposition of the iodide instead of the tris-one which appeared in the chloride and bromide. IR spectra showed that, although the hexa-hydrazine complex as a starting material contains only unidentate hydrazine coordinated by either one of terminal nitrogen atoms, all the reaction intermediates have bidentate one bridging between two nickel ions. In particular, it was of much interest that the decomposition of these hydrazine complexes was remarkably exothermic, a part of the reasons being discussed.
