Oxalatocuprate(ii) hexaammincobalt(iii) as a precursor of metastable solid solutions in the Co–Cu system

Abstract

The synthesis and characterization of the double complex salts [Co(NH3)6]2[Cu(C2O4)2]3·4H2O and [Co(NH3)6]2[Cu(C2O4)2]3·6H2O was carried out. Subsequent annealing led to the formation of metastable solid solutions.
