摘要: 本文水热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）(1),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=27.184（2）Å,b=9.5379（7）Å,c=21.7831（17）Å,α=90°β=97.5370（10）°,γ=90°,V=5599.06（104）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。Abstract: a new type of three-dimensional coordination polymer Sm（oba） 2（H2O）2/H2O（oba=4,4 ’two carboxy two benzyl ether）（1） was synthesized by hydrothermal synthesis,and its structure was analyzed by X-ray single crystal diffractometer.The results show that the single crystal is formed in the C2/c space group of monoclinic system,specific parameters:a=27.184（2）,B=9.5379（7）,C=21.7831（17）,alpha=90（10）,=90 degree,V=5599.06（104） 3.A three-dimensional supramolecular framework was formed by bridging trivalent samarium ions with 4,4’-dicarboxydiphenyl ether ligands.
