The heat capacity of the dichalcogenide: tungsten ditelluride, WTe2, was measured over the temperature range 5.5 < T/K < 329 using adiabatic calorimetry. Our results show that a phase transition is not present. However, an anomalous rise in the molar heat capacity Cp m occurs in the region 92 < T/K < 175. The molar entropy change of this rise amounts to ΔSm = (0.10±0.02) · R. The anomaly coincides with the temperature range where all the translational, librational, and internal vibrational modes become fully excited. The electronic molar heat capacity Tγm = (5.99±1.83) mJ · K−1·mol−1 and, for the lattice, the Debye characteristic temperature ΘD = (133.8 ± 0.06) K. Standard molar thermodynamic functions are presented at selected temperatures from 5 K to 335 K.
