摘 要:采用溶液合成方法,合成出2种新颖的铅和镉配合物[Pb(bipy)(NO3)(H2O)].NO3(1)和[Cd(phen)2(NO3)2](2)(phen=1,10-邻菲啰啉,bipy=2,2′-联吡啶).对它们进行了元素分析、红外光谱表征,并通过X射线单晶衍射测定了配合物的单晶结构.X射线单晶结构解析表明:配合物1属单斜晶系,P2(1)/n空间群,中心金属Pb(Ⅱ)为4配位;配合物2也属单斜晶系,Cc空间群,中心金属Cd(Ⅱ)为6配位;配合物1通过分子间氢键形成2D层状结构,而配合物2通过分子间氢键连接形成3D超分子结构.Complexes [Pb(bipy) (NO3) (HzO)] . NO3 (1) and [Cd(phen)z (NO3)2] (2) were synthesized by the reaction of Pb(NO3)2 and phen or Cd(NO3)2 . 4H2O and 2,2'-bipyridine with solution synthesis method at air co.ndition. They are characterized by element analysis, IR and X-ray diffraction analysis. Structural analysis shows that complex 1 belong to mon0clinic system, P2(1)/n space group,center atom Pb ( Ⅱ ) is four coordinate; complex 2 is also monoclinic system, Cc space group,center atom Cd (Ⅱ) is six coordinate. The molecules of the complex 1 were connected by hydrogen bonding interaction to a 2D layer structure, while the molecules of the complex 2 were connected by hydrogen bonding interaction to a 3D superamolecular structure.
