Title

Thermal Study of Pd(II) Complexes Containing Bis-(Diphenylthiophosphenyl) Methane

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.
