在无水乙醇中, 用吡咯烷二硫代氨基甲酸铵(APDTC)和1,10-邻菲咯啉(o-phen·H2O)与PrCl3·3.75H2O作用, 合成了三元固态配合物, 确定它的组成为Pr[(C5H8NS2)3(C12H8N2)].X粉末衍射说明它为一新相化合物.IR光谱说明配合物中Pr3+分别与3个APDTC的6个硫原子双齿配位, 同时与o-phen的2个氮原子双齿配位,配位数为8.TG-DTG分析显示其热分解为一步生成Pr2S3 + 2C.用微量热计测定了298.15 K下水合氯化镨及两个配体在无水乙醇中的溶解焓, 两个配体醇溶液的混合焓及不同温度下标题化合物液相生成反应的焓变.在实验和计算基础上, 得到了液相生成反应的热力学参数(活化焓、活化熵和活化自由能), 速率常数和动力学参数(表现活化能、频率因子和反应级数), 通过合理的热化学循环, 求得了298.15 K时标题化合物的固相反应焓变.
