中文摘要：

在水热条件下合成了两个Keggin型多金属氧簇构筑的有机无机杂化化合物：[CuⅠ（2,2＇-bipy）2]{[CuⅠ（2,2＇-bipy）2]2][PW12O40]}·4H2O（1）和{[（H3bpdc）3][PW12O40]·H2bpdc}·2H2O（2）,并通过元素分析、红外光谱、热失重曲线和单晶X-射线衍射等手段确定了其组成和结构。化合物1属于单斜晶系,P2（1）/n空间群,化合物2属于三斜晶系P 1空间群。化合物1中2,2＇-联吡啶-3,3＇-二羧酸（H2bpdc）经原位脱羧反应形成{[CuⅠ（2,2＇-bipy）2]2[PW12O40]}—阴离子和[CuⅠ（2,2＇-bipy）2]＋配位阳离子,并通过氢键和π-π堆积作用形成一维链状结构。化合物2中多酸阴离子和H2bpdc有机组分通过氢键和静电引力形成三维超分子网络。电化学研究表明,两种化合物都存在三步氧化还原过程。

英文摘要：

Two novel organic-inorganic hybrids constructed from Keggin polyoxometalate [CuⅠ（ 2,2＇-bipy）2]{ [CuⅠ（ 2,2＇-bipy）2]2][PW12O40]}·4H2O（ 1） and { [（ H3bpdc）3][PW12O40]·H2bpdc } ·2H2O（ 2） were synthesized under hydrothermal condition and characterized by elemental analysis,IR,TG,CV and single-crystal Xray diffraction. Compound 1 crystallized in a monoclinic crystal system,with space group of P2（ 1） / n,and compound2 crystallized in a triclinic crystal system,with space group of P 1. Compound 1 formed a 2D layered structure by hydrogen bond and π- π stacking,while compound 2 formed a 3D supramolecular architecture by hydrogen bond and electrostatic attraction. The cyclic voltammogram indicated that three couples of redox waves were observed on the compound 1 and 2 modified carbon paste electrode.
