摘　　要：应用低温固相反应法合成了稀土氯化物和邻苯二甲酸的三种配合物,并对它们进行了组成分析、TG-DTA、红外光谱、荧光光谱和摩尔电导等的测定,确定配合物的组成为RE2(HL)3C l3.16H2O(RE=N d,Eu,T b;HL=o-C6H4(COOH)(COO-)),与文献报道的液相反应所得的产物组成不同[1,2]。从配合物的荧光激发和发射光谱可以发现,铕、铽的邻苯二甲酸配合物均具有很好的发光性能,且铽的发光性能比铕的发光性能更好。另外,溶解性实验表明配合物可以溶于水、乙醇,不溶于乙醚、丙酮。this paper ,the solid state reactions between rare earth and o-phthalic acid are studied. The complexes are synthesized by one step solid state reaction at room temperature and the products are characterized by element analysis, IR spectra, fluorescence spectra, DT-TGA and molar conductivity. The compositions of complexes have been confirmed to be RE2（HL）3Cl3 · 16H2O （RE=Nd ,Eu, Tb;HL=o-C6H4（COOH） （COO^-））.In the fluorescence spectra of RE2 （HL）3Cl3 · 16H2O, Tb^3＋ complexes have a strongly luminescent property. In addition,the experiment of resolving indicates that the complexes can be resolved in water and alcohol.
