摘　　要：通过双三唑丁烷、2,3-吡嗪二酸与硝酸锌的自组装反应,合成了一种新型的具有二维波浪状结构的锌配合物，分子式为{[Zn（pzdc）（btb）0.5（H2O）2]·H2O}n（H2pzdc=2,3-吡嗪二酸，btb=双三唑丁烷），X-射线衍射分析表明该配合物具有3-连接的（6,3）拓扑结构.配合物的Zn^Ⅱ中心通过吡嗪二酸阴离子组装成一维之字链,而之字链之间又通过柔性的双三唑丁烷配体桥连成奇特的二维波浪状结构.通过分子内和分子间O-H…N和O-H…O的氢键作用,配合物最终形成三维的超分子结构.同时对配合物的焚光性质和热稳定性质进行了讨论.A novel two-dimensional wave-like Zn complex, formulated as {[Zn（pzdc）（btb）0.5 （H2O）2 ]·H2O}n （H：pzdc = 2, 3-pyrazinedicarboxylic acid, btb = bis（1,2, 4-triazol-1-yl）butane）, was synthesized by the self-assembly re-actions of btb and H2 pzdc with zinc nitrates. X-ray diffraction analysis reveals that the complex displays a 3-con- nected （6 , 3） topology. The central ZnH ions of the compound are assembled into 1D zigzag chains by pzdc2- anions, which are further linked by flexible btb bridges to form a special 2D wave -like layer. And a 3D supramolecular architecture is finally constructed by the iner- and intra-molecular hydrogen bonds of O-H …N and O-H …O. Luminescence and thermogravimetric analyses have also been investigated in detail.
