The TG-DTG and DTA study of dipositive platinum(II) complexes of the general formula [Pt(L-L)(dppmS2)](ClO4)2, where dppmS2 = Ph2P(S)CH2P(S)Ph2 and L-L = dppm (Ph2PCH2PPh2), dppe (Ph2PCH2CH2PPh2), and dppp (Ph2PCH2CH2CH2PPh2), were studied by thermogravimetric analysis from ambient temperature to 1000 graduate C in nitrogen atmosphere. The decomposition occurred in one stage for [Pt(L-L)dppmS2](ClO4)2, [Pt(L-L)dpppS2](ClO4)2 and [Pt(L-L)dppmS2](ClO4)2 complexes. The values of activation energy, E, frequency factor, A, reaction order, n, entropy change, delta S Not equal to , enthalpy change, delta H Not equal to , and Gibss free energy change, delta G Not equal to , of the thermal decomposition were calculated by means of Coats-Redfern method (CR), MacCallum-Tanner method (MC) and van Krevelen method (vK). The activation energy values obtained by CR, MC and vK methods were in good agreement with each other.
