The pressure of thermal dissociation of platinum tetrachloride by the first step PtCl4(s) = PtCl3(s) + 0.5 Cl2(g) was measured by the static method with a quartz membrane-gauge zero-pressure manometer. An approximating equation for the dissociation pressure vs. temperature was found. The enthalpy (52160±880 J mol-1) and entropy (72.1±1.6 J mol-1 K-1) of dissociation were calculated. The heat of formation found for platinum tetrachloride (-246.3±1.3 kJ mol-1) at 298.15 K agrees well with the value obtained by the calorimetric method (-245.6±1.9 kJ mol-1).
Outer-sphere electron transfer from platinum(II) to Keggin-type 12-tungstocobaltate(III) in the presence and absence of chloride ions

The reaction between Pt(II) and [CoIIIW12I 40]5- proceeds with two, one-electron steps involving formation of unstable Pt(III) followed by its reaction with another oxidant. The reaction rate is unaffected by the [H+] as there are no protonation equlibria involved with both the reactants whereas, chloride ion accelerates the reaction and the reaction follows chloride independent and dependent paths leading to a two term rate law, rate= {k1 + Kk 2 [Cl-]} [Pt(II)] [CoIIIW12O 40]5-. The chloride ion dependent path is due to rapid substitution of chloride ion on PtCl42-. The products formed have been found to be PtCl4(aq) and PtC6 2- in the absence and presence of chloride ion respectively. Increase in the ionic strength and decrease in the relative permittivity of the medium increase the rate of the reaction. This is due to the formation of an outer-sphere complex between the two reactants. The activation parameters in the presence and absence of chloride ions have also been determined and the values support the proposed mechanism.
