Studies on the solid state reactions of coordination conpounds——XLⅤⅢ.The effect of KSCN on the thermal decomposition of cobalt(Ⅲ)-ammine complexes

The evolved gaseous analysis (EGA),infrared spectra,and XRD have been applied to the study of solid state reactions of KSCN with five cobalt(Ⅲ)-ammine complexes:[Co- (NH_3)_5N_3]Cl_2,[Co(NH_3)_5(NO_2)]Cl_2,[Co(NH_3)_5(H_2O)]Cl_3,[Co(NH_3)_5Cl]Cl_2,and [Co(NH_3)_6]Cl_3 in a hydrogen atmosphere.It is found that the existence of KSCN shifts the thermal decom- position of these complexes to a lower temperature.The corresponding peak temperatures are near 140℃.The effect of KSCN is discussed and kinetic parameters of deammine reactions are calculated.
