摘　　要：采用水热法合成了一种新型配位化合物[Ni(Hpdc)(2,2’-bipy)(H2O)2].H2O(H3pdc=3,5-吡唑二甲酸,2,2’-bipy=2,2’-联吡啶)。用热重分析、元素分析、红外光谱对该配位化合物进行了表征,用X射线单晶衍射仪测定了其晶体结构。结果表明标题化合物属三斜晶系(空间群Pī),金属离子位于一个变形八面体的中心。镍(II)以六配位的方式,与三个氧原子和三个氮原子进行了配位。构成晶胞的四个配合物分子通过氢键相互连结,芳香环间未形成π-π相互作用。The compound, E Ni （Hpdc） （ 2,2＇ -bipy） （ H2O ） 2 ] · H2O （ H3 pdc = 3,5-pyrazoledicarboxylic acid, 2,2＇ bipy = 2,2＇ -bipyridine）, was prepared under hydrothermal conditions. The structure of the coordination complex was determined by X-ray single crystal diffraction and characterized by elemental analysis, IR spectrum and thermogravimet- ric analysis. The coordination complex crystallized in the triclinic system, with space group PL The metal ion was loca- ted in the centre of a distorted octahedron. The Ni（II） ion was six-coordinated with three oxygen atoms and three nitro- gen atoms. The four molecules that built up a cell unit were connected via hydrogen bonds while no π-π interactions were observed between aromatic rings.
