Cobalt(II) bis(oxalato)cobaltate(II) tetrahydrate (Co[Co(C2O4)] · 4H2O) was synthesized and characterized on the basis of elemental and spectral analysis. The thermal decomposition of the complex was investigated in air and nitrogen media. In air, complete dehydration of the complex occured at 251°, followed by rapid decomposition to a mixture of CO2O3 and Co3O4 at 300°; in nitrogen, dehydration occurred at 206°, followed by decomposition to a mixture of Co and CoC2O4, and finally to Co + CoO, at 394° and 420°, respectively. The activation energies for the dehydration and decomposition reactions in nitrogen and air media were evaluated and a tentative reaction mechanism for the thermal decomposition of the complex was proposed.
