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。

Abstract:

The compound, ［Ni(Hpdc)(2,2’-bipy)(H2O)2］·H2O (H3pdc=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 thermogravimetric analysis. The coordination complex crystallized in the triclinic system, with space group Pī. The metal ion was located in the centre of a distorted octahedron. The Ni(II) ion was sixcoordinated with three oxygen atoms and three nitrogen 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.

Key words: 3,5-pyrazoledicarboxylic acid; 2,2’-bipyridine; hydrothermal synthesis; metal-organic framework; crystal structure
