摘要 利用水热技术合成了一种未见报道的二维扩展结构化合物{[Cu2(2,2-′bipy)2(4,4-′bipy)]2[Cu(4,4-′bipy)][PW10(Ⅵ)W2(Ⅴ)O40]}(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:该晶体属于单斜晶系,P-1空间群;晶胞参数a=1.364 6(3)nm,b=1.402 2(3)nm,c=1.441 6(3)nm,α=63.78(3)°,β=87.06(3)°,γ=65.56(3)°,V=2.224(8)nm3,Z=1,R1=0.053 9,wR2=0.115 0. A new 2D extended structural {[Cu2 (2,2'-bipy)2 (4,4'-bipy) ]2 [ Cu ( 4, 4'-bipy) ] [PW10 (Ⅵ) W2 (Ⅴ)O40 ]} (bipy = bipyridine) has been synthesized under hydrothermal conditions and structurally characterized by IR, elemental analyses and single-crystal X-ray diffraction. The crystal date for this compound are the following: monoclinic, space group P-1,a=1.3646(3)nm,b=1.4022(3)nm,f=1.4416(3)nm,a=63.78(3)°,β=87.06(3)°,γ=65.56(3)°,V=2.224(8)nm^3,Z=1,R1=0.0539,wR2=0.1150.
