Abstract:
Transition metal sulfite hydrazine hydrates, MSO(3.x)N2H(4.y)H2O where M = Mn, Fe, Co, Ni and Zn have been prepared and characterized by chemical analysis, infrared spectra, thermoanalytical and combustion studies. The colours, x and y parameters of the complexes varied depending upon the preparation conditions. Thermal decomposition characteristics differ from metal to metal yielding metal oxides at relatively low temperatures.
