摘要：
The thermal decomposition of [Co(NH3)6][Fe(C2O4)3]•3H2O in hydrogen and helium atmospheres was studied. The thermal decomposition of the complex proceeds via the same four steps in a temperature range of 50—430 °C, regardless of the atmosphere. The thermolysis processes in inert and reductive atmospheres differ by the nature of the final solid products: a Co0.5Fe0.5 alloys is formed in a hydrogen atmosphere, and a mixture of iron and cobalt oxides is observed for an inert atmosphere. The major gaseous decomposition products are H2O, NH3, CO2, and CO. © 2015, Springer Science+Business Media New York.
