Low-temperature heat capacities of crystalline Ho(Gly)3Cl3 · 3H2O from 78 to 348 K

Heat capacities of the rare-earth complex with glycine [Ho(Gly)3Cl3 · 3H2O] were measured with a high-precision automatic adiabatic calorimeter over the temperature range from 78 to 348 K. In the experimental temperature range, the heat capacities increased in a smooth and continuous manner and no phase transition or thermal anomaly occurred. Therefore, the sample was stable in the above temperature range. The values of experimental heat capacities were fitted to a polynomial equation with least square method and the thermodynamic functions, (HT—H298.15) and (ST—S298.15), were calculated.
