A new chain europium complex [Eu(2,3-DFBA)3·(H2O)2]n(2,3-DFBA=2,3-difluorobenzoate) was synthesized by solvent method.X-ray single-crystal diffraction analysis revealed that Eu3+ ions were linked through 2,3-DFBA groups via alternate bidentate-bridging and tridentate chelating-bridging coordination modes to form a one-dimensional(1-D) polymeric chain.Each Eu3+ ion is eight-coordinated by six O atoms of five 2,3-DFBA ligands and two water molecules.The abundant hydrogen bonds between chains resulted in a two... 相似文献
