Abstract
Single crystals of platinum trichloride were grown for the first time. The IR spectrum of single-crystal PtCl3 was recorded. The pressure of thermal dissociation of PtCl3 was measured by the static method with a quartz membrane-gauge zero-pressure manometer. An approximating equation for the dissociation pressure vs. temperature (540 K ≤ T ≤ 775 K) for the reaction 2 PtCl3(s) → 2 PtCl2(s) + Cl2(g) was found. The enthalpy (123.1±1.7 kJ mol−1) and entropy (183.6±2.8 J mol−1 K−1) for the dissociation of PtCl3(s) were calculated at 298.15 K.
