Abstract

Thermogravimetric (TG) and derivative thermogravimetric (DTG) studies of [N(S 2CN-HR) 2] complexes (M = Ni, Pd, Pt; R = Bu n , Cx, Ph) in dynamic nitrogen atmosphere have been performed, to determine their modes of decomposition. All of the complexes showed similar TG profiles. Mass loss considerations at the main decomposition stages indicate conversion of the metal(II) dithiocarbamates to sulphides. Reaction orders in each case were estimated by the shape characteristics of the corresponding DTG curves. Finally, kinetic parameters (energy, entropy of activation and pre-exponential factor) were determined from the TG curves.
