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 C-p degrees (T), enthalpy H degrees(T) - H degrees(0), entropy S degrees(T) - S degrees(0) and Gibbs function G degrees(T)- H degrees(0), for the range from T -> 0 to 350K. The differential scanning calorimetry in temperature interval 298-1473 K was applied to measure temperatures of phase transition and melting of compound under study. The high-temperature X-ray diffraction in range 298-1073 K was used for the determining thermal expansion coefficients. (C) 2011 Elsevier B.V. All rights reserved.
