摘　　要：利用水热法合成了一种新型三维配位聚合物[Sm(oba)2(H2O)2]∙H2O(oba=4,4′-二羧基二苯醚),并通过X-射线单晶衍射仪对其结构进行了分析。结果显示,该单晶形成于单斜晶系C2/c空间群,具体参数:a=27.1840(2)Å,b=9.5379(7)Å,c=21.7831(17)Å,α=90°,β=97.5370(10)°,γ=90°,V=5599.1(8)Å3,Z=8,D=1.68864 g/cm3,F(000)=2808.0。三价钐离子通过4,4′-二羧基二苯醚配体桥连形成一个三维超分子框架结构。A novel three dimensional coordination polymer[Sm(oba)2(H2O)2]∙(H2O)[oba=4,4′-oxybis(benzo⁃ic acid)]was synthesized by hydrothermal method and its structure was analyzed by X-ray single crystal dif⁃fractometer.The results showed that the single crystal was formed in the C2/c space group of monoclinic sys⁃tem.The specific parameters were as follows:a=27.1840(2)Å,b=9.5379(7)Å,c=21.7831(17)Å,α=90°,β=97.5370(10)°,γ=90°,V=5599.1(8)Å3,Z=8,D=1.68864 g/cm3,F(000)=2808.0.Samarium ion formed a threedimensional supramolecular framework through 4,4′-oxybis(benzoic acid)ligand bridging.
