文中利用水热技术,成功合成了有机-无机杂化材料:[CuⅠ(2,2’-b ipy)(4,4’-b ipy)0.5]2[CuⅠ(4,4’-b i-py)]2[S iW12O40],并应用红外光谱、元素分析、单晶X-射线衍射等进行了表征.结果表明,标题化合物的基本结构单元是由一个双支撑的经典的Keggin型[S iW12O40]4-多氧阴离子形成一维Z字形链,该一维链又通过{CuⅠ(4,4’-b ipy)}nn+单元形成三维骨架.该晶体属于三斜晶系:P-1空间群;晶胞参数a=10.930(2),b=13.550(3),c=13.729(3),α=109.80(3)°,β=103.46(3)°,γ=98.69(3)°,V=1800.83(60)3,Z=2,R1=0.0697,ωR2=0.1576.
In this paper, the organic-inorganic hybrid materials were successfully synthesized by hydrothermal technique: [CuⅠ (2,2’-b ipy) (4,4’-b ipy) 0.5] 2 [CuⅠ (4,4’-b i- py)] 2 [SiW12O40], and characterized by IR, elemental analysis, single crystal X-ray diffraction, etc. The results show that the basic structural unit of the title compound is composed of a double-supported classical Keggin type [SiW12O40 ] 4-polyoxyanion forms a one-dimensional zigzag chain which in turn forms a three-dimensional framework by {CuI (4,4’-b ipy)} nn + units belonging to triclinic: P-1 space group ; Cell parameters a = 10.930 (2), b = 13.550 (3), c = 13.729 (3), α = 109.80 (3) °, β = 103.46 = 1800.83 (60) 3, Z = 2, R1 = 0.0697, ωR2 = 0.1576.
