英文摘要A solid complex of rare-earth compounds with alanine, [ErY(Ala)(4)(H2O)(8)](ClO4)6 (Ala=alanine), was synthesized, and a calorimetric study and thermal analysis for it was performed through adiabatic calorimetry and thermogravimetry. The low-temperature heat capacity of [ErY(Ala)(4)(H2O)(8)](ClO4)(6) was measured with an automated adiabatic precision calorimeter over the temperature range from 78 to 377 K. A solid-solid phase transition was found between 99 and 121 K with a peak temperature at 115.78 K. The enthalpy and entropy of the phase transition was determined to be 1.957 kJ mol(-1), 16.90 J mol(-1) K-1, respectively. Thermal decomposition of the complex was investigated in the temperature range of 40similar to550degreesC by use of the thermogravimetric and differential thermogravimetric (TG/DTG) analysis techniques. The TG/DTG curves showed that the decomposition started from 120 and ended at 430degreesC, completed in three steps. A possible mechanism of the thermal decomposition was elucidated.
