摘　　要：BaCl2.2H2O和配体3,4-吡啶二酸在溶剂热条件下反应生成了配合物[Ba2(pdc)2(H2O)3]n(1)(H2pdc=3,4-吡啶二酸),用单晶X-射线、元素分析和FT-IR对生成的晶体进行了表征。Ba1和Ba2分别采取了八配位扭曲四方反棱柱和十配位的双帽四棱柱几何构型,整个pdc2-作为四齿桥联配体连结4个不同的Ba(Ⅱ)原子形成二维网结构,O-H…N氢键将二维网结合在一起形成三维结构。还研究了配合物1的荧光和热重性质。Solvothermal reaction of BaCl2O 2H2O with 3,4-pyridinedicarboxylic acid afforded a new inorganic- organic hybrid framework, [Ba2（pdc）2（H2O）3]n （1） （Hzpdc=3,4-pyridinedicarboxylic acid）. This complex has been fully characterized by single crystal X-ray diffraction, elemental analysis, and IR spectrum. X-ray analysis shows that complex I features a two-dimensional network （2D）. Bal takes eight-coordinated distorted square antiprism geometry. Ba2 takes ten-coordinate distorted dicapped square prism coordination geometry. The whole pdc2- anion connects four different Ba（Ⅱ） atoms, giving rise to a 2D network structure. The three-dimensional structure is formed by O-H... N hydrogen bonding interactions. Thermal stability and luminescent property of compound 1 have also been investigated. CCDC： 887479.
