Na10 {[(Cu (H2O)3)2 (WO2)2 (BiW9O33)2]}·23.5H2O (1), a none-dimensional inorganic polyoxometalate chain constructed from dimeric bismuth tungstate, was synthesized and characterized by IR spectrum, elemental analysis, UV spectrum, fluorescence spectrumand single-crystal X-ray diffraction. Crystal data for compound 1 were as follows:space group, monoclinic, P2(1), a=1. 2865(26) nm, b=2. 52563(49) nm, c=1. 62185(41) nm,β=94. 03(4)°, V=5. 20836(1093) nm3, Z=2, R1=0. 0539, ωR2=0. 1189, Dc=3. 36 g/cm3. In the UV spectrum, there were two characteristic peaks of Keggin polyoxoanion at 236 and 293 nm.%用常规法合成了一种新的一维链状结构的夹心型多酸Na10{[(Cu(H2O)3)2(WO2)2(BiW9O33)2]}·23.5H2O(1),并对其进行X射线单晶结构分析、元素分析、红外光谱和紫外光谱表征。结果显示,该多酸阴离子属于单斜晶系, P2(1)空间群,晶胞参数a=1.2865(26) nm, b=2.52563(49) nm, c=1.62185(41) nm,β=94.03(4)°, V=5.20836(1093) nm3, Z=2, R1=0.0539,ωR2=0.1189, Dc=3.36 g/cm3。紫外光谱在236和293 nm有两个多酸特征的吸收峰。
