在无水乙醇中,用铜试剂(NaEt2dtc·3H2O)和邻菲咯啉(o-phen·H2O)与水合氯化铒(ErCl3·3.46H2O)作用,制得三元固态配合物. 化学分析和元素分析确定其组成为Er(Et2dtc)3(phen). IR光谱研究表明,配合物中Er3+与NaEt2dtc中的硫原子双齿配位,同时与o-phen中的氮原子双齿配位. 用微热量计测定了标题配合物在298.15 K下的液相生成反应焓变ΔrHθm(l)为(-13.857±0.096) kJ/mol,计算出它的固相生成反应焓变ΔrHθm(s)为(119.662±0.695) kJ/mol;得到了标题配合物液相生成反应的热动力学和动力学参数;测定了固态配合物的恒容燃烧能ΔcU为(-18 436.62±9.11) kJ/mol,其标准摩尔燃烧焓ΔcHθm和标准摩尔生成焓ΔfHθm经计算分别为(-18 455.83±9.11) kJ/mol和(-329.48±9.91) kJ/mol.
