摘要：
The thermolysis of the complexes [Co(NH3)(6)](2)C2O4[Cu(C2O4)(2)](2) (I) and [Co(NH3)(6)]Cl[Cu(C7H4O3)(2)] (II) in air and hydrogen at 200, 350, and 500 degrees C and the composition and properties of the thermolysis products are considered. The oxidative thermolysis of the complexes yields mixtures of cobalt and copper oxides, including mixed ones. The reductive thermolysis of the complexes yields a Co+Cu bimetallic powder in the case of compound I and a Co+Cu+C powder in the case of compound II. The thermal behavior of the complexes is governed by the nature of the ligand coordinated to the copper atom. The observed data are explicable in terms of the properties of this ligand. The chemistry of the oxidative and reductive thermolysis is discussed.
