Heat capacities of solid SmCl3 and TmCl3 were measured by differential scanning calorimetry in the ternperature range from 300 K up to the respective melting temperatures. The heat capacity of liquid SmCl3 was also investigated. These results were compared with literature data and fitted by a polynomial temperature dependence. The temperature coefficients were given. Additionally, the enthalpy of fusion of SmCl3 was measured. Furthermore, by combination of these results with the literature data on the entropy at 298.15 K, S0m(LnCl3, s, 298.15 K) and the standard molar enthalpy of formation of Δform H0m(LnCl3,s, 298.15 K), the meruiodynaniic functions were calculated up to T = 1300 K.
