摘要
合成了ⅡA,ⅣA,ⅤA族元素为取代原子的3个系列钨铜杂多配合物.经ICP,TG曲线确定其化学式为K8[CuZ(OH2)W11O39].xH2O和K17,18[Z′(CuW11O39)2].xH2O(Z=Mg,Ca;Z′=Sr,Ba,Sn,Pb,Sb,Bi).通过TG-DTA,IR,XRD,XPS,183W-NMR等手段对合成配合物结构进行了表征,并对其进行了讨论.结果表明,新配合物具有典型的Keggin结构,且主族元素进入到配合物的骨架中.由于新配合物中CuⅡ具有顺磁性,导致XPS,183W-NMR的测试结果表现出特殊性;用循环伏安法测定了新配合物的电化学性质,表明均为可逆氧化还原过程,还对导电性和热稳定性进行了研究.
Three series of heteropolytungstocopper compounds containing ⅡA, ⅣA and ⅤA element have been prepared. The molecular formulas are confirmed as K8 [CuZ（OH2） W11O39 ]·xH2O and K17.18[Z＇ （CUW11O39）2]xH2O（Z= Mg, Ca; Z＇= Sr, Ba, Sn, Pb, Sb, Bi） by ICP and TG. Their structures are characterized by TG-DTA, IR,XRD, XPS,183 W-NMR measurements. The results show that the new compounds are of Keggiu structure, and the main group elements have already entered into the skeletons of new compounds. Because the Cuu in the compounds is paramagnetic, the special properties are shown in the results of XPS,^183W-NMR, and discussed in the paper. Furthermore, according to Cyclic Voltammetry, their electrochemical properties are determined, the result indicts that all the redox processes are reversible, the conductivity and the thermalstabilities of the compounds are also studied,
