Preparation and Thermal Decomposition of Copper(II) Complexes with 4-Methylimidazole

Simple and mixed compounds of the formulae Cu(4-Meim)2, CuSal(4-Meim), CuSal(4-Meim)2 and CuSalox(4-Meim)2, where 4-Meim=4-methylimidazole, Sal=(OC6H4COO)2−, Salox=(OC6H4CHNO)2− have been prepared. Thermal decomposition reactions have been established on the basis of thermal and X-ray analyses of these compounds. The pyrolysis proceeds in several (3–4) stages connected with the mass loss and exothermic effects. As a result of the last stage of decomposition CuO is formed.
