英文摘要: A terbium complex with glycine Tb(Gly)(2)Cl-3 center dot 3H(2)O was synthesized and its IR spectrum was determined. The heat capacity of the complex was measured with a high-precision automatic adiabatic calorimeter over the temperature range from 81 to 378 K. From 170 to 247 K, two solid-solid phase transitions occurred at 186.054 and 244.063 K, respectively. Thermal decomposition of the complex was studied by thermogravimetric (TG) techniques and a possible mechanism for the decomposition was suggested. By isoperibol solution-reaction calorimetry, the standard molar enthalpy of formation of Tb(Gly)(2)Cl-3 center dot 3H(2)O was derived to be -(3109.5 +/- 3.1) kJ.mol(-1).
