摘　　要：水热法合成新型配位聚合物[Zn_(2)(pydc)_(2)]_(n)(1)(H_(2)pydc=吡啶-2,6-二甲酸),用红外光谱、元素分析和单晶X-射线衍射进行表征.化合物属单斜晶系,C2/c空间群,晶胞参数:a=1.39270(12)nm,b=1.39529(12)nm,c=1.65401(14)nm,β=100.909(2)■.中心离子Zn(Ⅱ)具有三种配位构型,分别处于变形八面体、四方锥、四面体配位环境.相关的Zn(Ⅱ)离子形成两种不同的一维链状结构,临近的一维链进一步通过pydc^(2-)桥联形成二维网状结构.固体荧光测试表明,1在室温下发射蓝色荧光.One novel coordination polymer[Zn_(2)(pydc)_(2)]_(n)(1)(H_(2)pydc=2,6-pyridinedicarboxylic acid)has been synthesized by hydrothermal method and characterized by IR,elemental analysis and single crystal X-ray diffraction.The compound crystallizes in monoclinic system,space group C2/c with a=1.39270(12)nm,b=1.39529(12)nm,c=1.65401(14)nm,andβ=100.909(2)■.The central Zn(Ⅱ)ions locate in three different coordination environments including distorted octahedral,tetragonal pyramid and tetrahedral configurations.The related Zn(II)ions form two different one-dimensional chain structures,and the adjacent one-dimensional chains are further bridged by pydc2-to generate a two-dimensional network.The solid state fluorescence test shows that 1 emits blue fluorescence at room temperature.
