As a result of the interaction of nickel perchlorate with ethylenediamine, imidazole, and semicarbazide, complex compounds Ni(En) 3 (ClO 4 ) 2 , Ni(Im) 6 (ClO 4 ) 2 , and Ni(SC) 3 (ClO 4 ) 2 have been obtained, the structure and composition of which were confirmed by elemental analysis and by the method of the infrared spectroscopy of frustrated total internal reflection. The kinetics of the thermal decomposition of synthesized compounds in an inert medium was studied within the framework of the traditional method of thermal analysis in a helium atmosphere at a rate of the heating of samples of 5°C/min and under conditions of their high-speed heating (>100°C/min) with simultaneous determination of the composition of gaseous products of thermal decomposition of the material.
