中文摘要：

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.

英文摘要：

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.
