英文摘要Heat capacities of the complex of rare-earth element with valine [Sm(Val)Cl3 center dot 6H(2)O] were measured with a high-precision automatic adiabatic calorimeter over the temperature range from 80 to 376 K, and the thermodynamic unctions (H-T-H-298.15 and S-T-S-298.15) were calculated. A large step in heat capacity was detected around 308 K and this may be attributed to a glass transition corresponding to freezing of structural disorder. Thermal decomposition of this complex as studied by thermogravimetric (TG) technique and a possible mechanism for the decomposition was suggested.
