Abstract
Organometallic complexes of transition metals with inorganic anions are considered as promising precursors for the synthesis of nanoscale materials used in various fields, including chemical catalysis. In this work, organometallic complexes of nickel, iron, and copper with an organic ligand (imidazole) and with an inorganic ligand (nitrate anion) were synthesized and characterized. The kinetic parameters of thermal decomposition of the synthesized organometallic complexes were determined by low heating rate thermogravimetric analysis and high-speed dynamic mass spectrometric thermal analysis. The main gaseous products of thermal decomposition of the complexes under high-speed heating were identified. The chemical and phase composition of condensed combustion products of organometallic complexes in air was studied.
