Abstract:	Summary The thermal decomposition of [CoCl₂(-pic)₂] was investigated over the 108°C to 222°C range and the Intennediates CoCl₂(-pic) (s) and CoCl₂ (s) were observed, with the evolution of (-pic) (g). Quantitative thermodynamic and kinetic data were obtained by performing dynamic and isothermal studies on the complex Additional thermodynamic data were obtained by studying the CoCl₂/-pic system in acetone. The effect of the methylsubstituent on the metal-donor-N bond as well as on the thermodynamic quantities were discussed.
