摘　　要：制备了以3-((4,6-二甲基-2-嘧啶基)硫代)-丙酸(HL)和菲咯啉(Phen)为配体的2个三元稀土配合物[Eu(L)_(3)(Phen)]_(2)·2H_(2)O(1)和[Tb(L)_(3)(Phen)]_(2)·2H_(2)O(2),并对其结构进行了表征。单晶X射线衍射分析表明它们是同构的。2个稀土离子(Ln)由4个羧酸配体桥接,形成二聚体排列。其余2个羧酸配体和Phen以双齿螯合方式与Ln配位。Ln的配位数为9,具有扭曲的单端方形反棱柱配位多面体构型。固态光致发光测试表明,这2种配合物都显示了金属中心的特征发射带。Two ternary lanthanide complexes,[Eu(L)_(3)(Phen)]_(2)·2H_(2)O(1) and[Tb(L)_(3)(Phen)]_(2)·2H_(2)O(2),based on 3-((4,6-dimethyl-2-pyrimidinyl)thio)-propanoic acid(HL) and 1,10-phenanthroline(Phen) were prepared and structurally characterized.Single-crystal X-ray diffraction analyses reveal that they are isostructural.Two lanthanide ions(Ln) are bridged by four carboxylate ligands.The rest two carboxylate ligands and Phen coordinate with Ln with bidentate chelating mode,forming the dimeric arrangement.The coordination number of Ln is nine with a distorted mono-capped square antiprismatic coordination polyhedron.The solid-state photoluminescent measurements suggest that both complexes showcase the characteristic emission bands of the metal center.CCDC:2129656,1;2129657,2.
