摘　　要：以元件组装方法合成了Cu4(HL)4·2H2O簇合物(H2L=N-乙氧羰基-N′-o-硝基苯基硫脲)。用X射线单晶衍射技术、核磁共振谱、红外光谱和元素分析等确定了簇合物及其相应组装元件的晶体结构和化学组成,并对簇合物的电催化性质进行了检测。结果表明,该簇合物由4个Cu(I)以M-M键构成簇核,4个硫脲配体分别以硫羰基硫原子和氮原子配位于Cu(I)构成簇合物配位结构,DPV分析显示该簇合物对O2具有较高催化活性。A Cu4 cluster compound, Cu4（HL）4·2H2O, （H2L=N-ethoxycarbonyl-N＇-o-nitrophenylthiourea）, was synthesized in the way of component assembly. Structures and chemical compositions of the cluster compound and its corresponding component were determined by single crystal X-ray diffraction analysis, elemental analysis, FTIR, 1H NMR etc., and its electro-catalysis was also characterized. The experimental results show that the core of the cluster compound is composed by four Cu（I） linked with M-M bonds, and the Cu（I） are coordinated by 4 thiourea ligands with thiocarbonyl sulfur atom and nitrogen atom, respectively. DPV Electro-catalysis shows that the cluster compound is of high O2 catalysis activation. CCDC： 945182, Cu（H2L）2Cl·H2O; 602859, Cu4（HL）4·2H2O.
