摘要 利用水热技术合成了一种新型的二维扩展结构化合物[CuⅡ(2,2′-bipy)2]2[SiW12O40].2H2O(bipy=联吡啶),并采用红外光谱、元素分析、单晶X射线衍射对其进行了表征.结果表明:该晶体属于正交晶系,Pbca空间群;晶胞参数a=1.8361(4)nm,b=1.7075(3)nm,c=2.0541(4)nm,α=90°,β=90°,γ=90°,V=6.440(2)nm3,Z=4,R1=0.1030,wR2=0.2116. A new 3D extended structural [CuⅡ(2,2'-bipy)2]2[SiW12O40]·2H2O(bipy=bipyridine) has been synthesized under hydrothermal conditions and structurally characterized by IR,elemental analyses and single-crystal X-ray diffraction.The crystal data for this compound are the following:orthorhombic,space group Pbca,a=1.836 1(4) nm,b=1.707 5(3) nm,c=2.054 1(4) nm,α=90°,β= 90°,γ= 90°,V=6.440 (2) nm3,Z=4,R1=0.103 0,wR2=0.211 6.
