Thermal properties of 3 P chalcogenides were determined by adiabatic calorimetry and yielded entropies at 298.15°K. for P4S3, P4Se3, and P4S10 of 48.60, 57.26, and 91.24 cal./degree, resp. The P4S3 transforms to a plastically crystalline state at 313.90°K. with ΔSt = 7.85 cal./mole degree and P4Se3 shows an anomalous increase in heat capacity suggesting such an effect slightly above 350°K. Diffraction data on P4S3 provided coefficients of thermal expansion on both phases and confirmation of the plastically crystalline nature of the crystal I phase.
