The thermal decomposition kinetics of the solid complexes Cd(S2CNR2)2, where R=C2H5, n-C3H7, n-C4H9 or iso-C4H9, was studied by using isothermal and non-isothermal thermogravimetry. The super-imposed TG/DTG/DSC curves revealed that thermal decomposition reactions occur in the liquid phase. The kinetic model that best fitted the experimental isothermal TG data was the one-dimensional phase-boundary reaction-controlled process R1. The thermal analysis data suggested the thermal stability sequence Cd(S2CNBu2n)2>Cd(S2CNPr2n)2 >Cd(S2CNBu2i)2>Cd(S2CNEt2)2, which accords with the sequence of stability of the apparent activation energies.

The standard molar enthalpies of formation of crystalline n2)2> (M = Zn, Cd or Hg), determined through reaction-solution calorimetry at 298.15 K, were found to be -471.23 +/- 3.90, -440.74 +/- 3.79 and -319.29 +/- 3.38 kJ mol-1, respectively.The corresponding molar enthalpies of sublimation, 107 +/- 3, 123 +/- 3 and 195 +/- 3 kJ mol-1, were estimated by means of differential scanning calorimetry.From the standard molar enthalpies of formation of the gaseous chelates, -364 +/- 5, 318 +/- 5 and -124 +/- 5 kJ mol-1, the homolytic and heterolytic mean metal-sulphur bond enthalpies were calculated.The homolytic enthalpies decrease from zinc to mercury, while the heterolytic values are almost constant.
