摘　　要：由氯化钙与磺基水杨酸溶解在乙醇水溶液中反应生成磺基水杨酸钙配位聚合物{[Ca(H_2L)2·H_2O]·2H_2O}n(1)(H_2L-=磺基水杨酸一价阴离子).通过X-射线衍射单晶结构、荧光性质和介电性质测定,结果表明:聚合物1含有一个二维无限的[CaO_2]n平面结构,H_2L-竖立在平面的上下面,在H_2L-上的羧基和羟基未参与配位,但与层间结晶水形成强氢键,构筑成三维超分子结构;聚合物1发射强的蓝色荧光,介电常数在-180℃至0℃范围内保持不变.A calcium sulfonaite coordination polypmer { [Ca（H2L）2·H2O]·2H2O}n（1）（H2L-=5-sulfosalicylate anion） has been synthesized by reaction of calcium chloride with 5-sulfosalieylic acid in ethanol aqueous. 1 has been characterized by single crystal X-ray crystallography, luminescence and dielectric constant （e） measurement. The results showed that 1 was constructed by an infinity 2D inorganic framework [ CaO2 ] n with organic H2L- on both sides. The uncoordinated carboxyl group and hydroxyl group on H2L- could form strong hydrogen bonds with crystal water contained in the interlayer, and thus constructed into a three-dimensional supramolecular structure. 1 could emit strong blue fluorescence, and its dielectric constant （e） of temperature dependence from - 180℃ to 0℃ maintains unchanged.
