摘　　要：按照文[1]献合成了三元配合物[La(C_9H_6NO)_2(C_6H_5COO)]·H_2O,通过红外光谱进行表征.利用Hess定理设计了配位反应的热化学循环,并在常压、298.15 K下,分别测定了七水氯化镧、苯甲酸、8-羟基喹啉以及配合物在混合溶剂中的溶解焓,求出了298.15 K时配位反应的反应焓,并进一步计算出了三元配合物[La(C_9H_6NO)_2(C_6H_5COO)]·H_2O的标准摩尔生成焓.[La（C9H6NO）2（C6H5COO）]·H2O were synthesized and characterized by IR according to a document. In terms of Hess Law,a thermochemical cycle of reaction was designed, the dissolution enthalpies of different reactants and products systems were mensurated in a mixed solvent by micro-calorimetry under normal pressure and at a temperature of 298. 15K, the reaction enthalpy and the standard molar enthalpy of formation of [La（C9H6NO）2（C6H5COO）]·H2O was evaluated.
