The mercury(II) bis(dialkyldithiocarbamate) complexes, Hg(S 2CN-R2)2, in which R=ethyl, n-propyl, n-butyl and iso-butyl were characterized by TG, DSC, FTIR and elemental analysis. The TG curves presented two thermal decomposition stages; the first stage can be attributed to the partial decomposition of ligand and also to mercury sulfide decomposition. The second stage is representative for the decomposition of ligand fragments. The overlaid TG/DSC curves indicated that the decomposition of the complexes takes place the liquid phase. According to the isothermal kinetic data the phase-boundary controlled kinetic models describes the best the decomposition of complexes. The data obtained by the Ozawa method suggest the following stability order for the complexes: iBu>nPr>nBu>Et.
