Abstract

The TG-DTG and DTA study of dipositive palladium(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 (Ph ₂PCH₂CH₂PPh₂) and dppp (Ph ₂PCH₂CH₂CH₂PPh₂), were studied by thermogravimetric analysis from ambient temperature to 1273 K in nitrogen atmosphere. The decomposition occurred in one stage for all complexes. The values of activation energy, E, frequency factor, A, reaction order, n, entropy change, ΔS^≠, enthalpy change, ΔH ^≠ and Gibss free energy, ΔG^≠ of the thermal decomposition were calculated by means of Coats-Redfern (CR), MacCallum-Tanner (MC) and Horowitz-Metzger (HM) methods. The activation energy value obtained by CR, MC and HM methods were in good agreement with each other.
