摘　　要：在乙醇溶液中合成了铕与间苯二甲酸二元配合物和铕与间苯二甲酸、1,10-邻菲罗啉的四元配合物。通过元素分析、热分析、红外光谱,对其组成进行了表征。结果表明:其基本组成二元配合物为Eu2(C6H4(COO)2)6.4H2O、四元配合物为Eu(C6H4(COO)2)3.Phen.NO3.K.6H2O。红外光谱测定其配合物的羧基氧与铕是桥式配位。配合物的荧光光谱分析表明:配合物在613 nm处出现了Eu(Ⅲ)的特征发射。The europium binary and quaternary complexes with m-phthalic acid and 1,10-phenanthroline were prepared in the ethanol solution.The chemical composition and structure of compounds were characterized by IR,elemental analysis,TG-DTA.The results show that the tentative compositions of the binary and quaternary complex are Eu_2(C_6H_4(COO)_2)_6·4H_2O and Eu(C_6H_4(COO)_2)_3·Phen·NO_3·K·6H_2O.The IR result shows that the oxygen from the carboxyl group is coordinated to the europium in bridging mode.The analyzed result of fluorescent spectrum shows the complex has a characteristic emission at 613 nm.
