Аннотация In the present work the temperature dependences of pentalead tris(vanadate) chloride heat capacity have been measured for the first time in the range from 7 to 350 K. The experimental data were used to calculate standard thermodynamic functions, namely the heat capacity Cp◦ (T), enthalpy H◦(T)−H◦(0), entropy S◦(T)−S◦(0) and Gibbs function G◦(T)−H◦(0), for the range from T→0 to 350 K. The differential scanning calorimetry in temperature interval 298–1473K was applied to measure temperatures of phase transition and melting of compound under study. The high-temperature X-ray diffraction in range 298–1073K was used for the determining thermal expansion coefficients.
