Summary

The thermal decompositions of [MnCl2(py)2] and [NiCl2(py)2] were investigated and the following dissociation reactions were observed: [MnCl2(py)2](s)→MnCl2(py)(s)+(py)(g) [MnCl2(py)2](s)→MnCl2(s)+2(py)(g) and [NiCl2(py)2](s)→NiCl2(py)(s)+(py)(g) [NiCl2(py)2](s)→NiCl2(s)+2(py)(g). Quantitative thermodynamic as well as kinetic data were obtained by performing dynamic and isothermal studies on the complexes. The DSC studies provided evidence for the existence of the additional intermediates [Ni3Cl6(py)2] and [Mn3Cl6(py)2], which could not be obtained from the dynamic and isothermal studies.
