通过水热合成得到了一个新颖的包含四核铜配合物的无机-有机杂化化合物[CuCl(H2O)4)][CuCl(H2O)(Phen)][{(CuPhen)2Cl2}2(bdc)]2[P2W18O62]·5H2O(1)(Phen=1,10-phenanthroline和bdc=1,4-benzenedicarboxylate),对其进行了元素分析、红外光谱、热重、电化学等表征,并用X-射线单晶衍射测定了它的晶体结构。化合物1含有由Cl和bdc桥连的四核铜配合物阳离子[{(CuPhen)2Cl2}2(bdc)]2+。此外,化合物1的电化学研究表明其对亚硝酸的还原具有很好的电催化活性。

A novel hybrid compound [CuCl（H20）4）l[CuCl（H20）（Phen）][{（CuPhen）2C12}2（bdc）]2[P2W18O62]·5H2O （1） （Phen=1,10-phenanthroline and bdc=l,4-benzenedicarboxylate）, containing muhinuclear CuH complex cations, has been obtained in hydrothermal conditions and characterized by IR, elemental, thermogravimetric, electrochemical and single-crystal X-ray diffraction analysis. The main structural feature to this compound is the copper-Phen complex moieties which compose new tetranuclear copper-Phen complex cation [{（CuPhen）2C12}2（bdc）]2＋ bridged by C1 and bdc ligands. Furthermore, a compound 1-modiffied carbon paste electrode （1-CPE） displays the good electrocatalytic activity toward the reduction of nitrite. CCDC： 952036.
