The thermal decomposition of metal complexes—XX

Abstract The thermal dissociation of Cu(NH3)4(NO3)2, Cu(MeNH2)4(NO3)2, Cu(EtNH2)4(NO3)2· 2H2O, and Cu(i-PrNH2)4(NO3)2 was studied using TGA, DTA and MSA techniques. All of the complexes dissociated from the fused state in the temperature range of 150°–250°C. The primary dissociation products were copper(II) oxide, nitrogen, nitrogen(I) oxide, an alcohol (except for the ammonia complex) corresponding to the original amine, and an alkene hydrocarbon having the same carbon chain as the original amine. A mechanism is proposed to explain the dissociation reaction of the complexes.
