Ni(2,2'-bipy)(SeO_4)(H_2O)_2新型化合物的合成与表征

Synthese,Characterization and Crystal Structures of Ni(2,2'-bipy)(SeO_4)(H_2O)_2

在异丙醇溶剂下,NiCl_2·2H_2O、SeO_2、2,2'-联吡啶、咪唑以溶剂热方法来反应,生成了化合物Ni(2,2’-bipy)(SeO_4)(H_2O)_2(1)。在化合物1中,镍具有[NiO_4N_2]八面体配位构型,两个氮来自2,2'-联吡啶,而四个氧原子有两个是来自两个硒酸根,还有两个氧原子则是来自两个配位水。化合物1是一种一维链结构,链内结构是以[NiO_4N_2]八面体与SeO_4交替形成。一维链的一侧存在氢键作用从而形成双链,而另一侧交叉排列的2,2'-联吡啶之间则存在π-π作用形成层。

In this study, NiC12 · 2H2O, with SeO=, 2,2＇-bipy and imidazole, were used to react with organic solvent i-PrOH to form a compound Ni（2,2＇ -bipy） （SeO4） （H2O）2 （1）. The Ni of compound 1 is octahedrally coordinated by two nitrogen atoms of 2,2＇ -bipy, two oxygen atoms of SEO42 - and two oxygen atoms of aqua ligands. Thus, the NiO4N2 octahedra forms. The compound 1 is a one -dimensional chain structure, which is formed by the alternation of [ NiO4N2 ] octahedra and SeO4. Such chains are further interlinked by hydrogen bonds and π-π interactions to form a layer. These layers are further interacted through weak Van der Waals force.
