摘要： 合成了13种由稀土离子(La3+、Pr3+、Nd3+、Sm3+-Yb3+和Y3+)与马来酸(C4H4O4)和邻菲咯啉(Phen)形成的三元配合物。元素分析和微量水分测定确定其组成为Ln2(C4H2O4)3(Phen)2·4H2O.研究了它们的紫外,红外吸收光谱,探讨了配合物的荧光性质及热稳定性。

Abstract: Thirteen ternary complexes were synthesized by the reaction of rare earth ions(Ⅲ) (La3+、Pr3+、Nd3+、Sm3+—Yb3+ and Y3+) with maleic acid and 1,10-phenanthroline(Phen) in C2H5OH-H2O(1:1) solution. Elemental analyses indicate that the complexes have a composition of Ln2(C4H2O4)3(Phen)24H2O. UV, IR spectra luminescence and thermal properties of the complexes also have been reported.

Key words: rare earth, ternary complex, maleic acid, 1,10-phenanthroline, synthesis, spectral behavior
