LOW-TEMPERATURE HEAT-CAPACITY OF RBASF6

Heat capacity of RbAsF6 was measured in the temperature range 10-320 K by adiabatic calorimetry. No anomalies in heat capacity were observed . The following standard values of the thermodynamic parameters of RbA sF6 were obtained: C-p(0)(298.15 K) = 173.8 +/- 0.4 J/(mol K), S-0(298 .15 K) = 224.5 +/- 0.5 J/(mol K), H-0(298.15 K) - H-0(0) = 31470 +/- 7 0 J/mol, and Phi(0)(298.15 K) = 119.0 +/- 0.2 J/(mol K).
