The heat capacity of Bi12.5Lu1.5ReO24.5 was measured for the first time in the temperature range of 175–550 K. Calorimetric experiments were performed using differential scanning calorimetry (DSC). Temperature dependence of the molar heat capacity in the form C p,m o (T) = 324.87 + 3.0307 T − 4.5672 × 10−3 T 2 + 2.7319 × 10−6 T 3 was derived from experimental data. The enthalpy and entropy increments (H m o (T) − H m o (298.15), S m o (T) − S m o (298.15)) were evaluated from heat capacity data (T = 175–550 K). The temperature dependences of formation enthalpy and Gibbs energy for Bi12.5Lu1.5ReO24.5 were calculated based on measured heat capacities and data on standard formation enthalpy obtained by us earlier.
