In this article, we chose 1,3bis (4’carboxylphenoxy) benzoic acid and 1,3bis((4’carboxylphenyl)oxy)benzoic acid as the major ligand coordinating with metal ions by hydrothermal methods, and synthesized tw o new coordination polymers, which are shown below:[Eu2(L1)2 (H2O)3] (1) and [Eu(L2)(H2O)2] (2). Their structures were characterized by singlecrystal Xray diffraction, and then they were further characterized by elementary analysis, IR, TGA, fluorescence and magic properties.
