英文摘要The heat Capacities Of the two complexes [La-2(Gly)(6)(H2O)(4)](ClO4)(6) and [Ho-2(Gly)(6)(H2O)(4)](ClO4)(6).2H(2)O (Gly=glycine), were measured by adiabatic calorimetry in the temperature row from 78 to 375 K. A solid-solid phase transition was found between 322.87 and 342.29 K for [Ho-2(Gly)(6)(H2O)(4)](ClO4)(6).2H(2)O, and the peak temperature, the enthalpy and the entropy of the transition were obtained to be 330.94 K, 11.65 kJ(.)mol(-1) and 35.20 J (.) K-1 . mol(-1), respectively. No indication of any phase transition or thermal anomaly was observed for [La-2(Gly)(6)(H2O)(4)](ClO4)(6). Thermal stabilities of the two complexes were investigated by thermogravimetry in the temperature range of 40-800degreesC. The possible mechanism for the thermal decompositions were proposed according to the TG and DTG curves.
