通过水热合成技术合成了一个由经典的Keggin和pseudo-Keggin双阴离子,以4,4’-bipy为有机模板剂共同构筑成结构新颖的三维超分子化合物(4,4’-bipy)8H9[PW12O40]2[PW12O40]·11H2O,对其进行了IR、XPS等表征,单晶X射线衍射分析结果表明,该化合物属于单斜晶系,P1—空间群,晶胞参数:a=1.1843(13)nm,b=1.9218(2)nm,c=2.1036(2)nm,α=63.3420(10)°,β=74.148(2)°,γ=79.721(2)°。由Keggin簇阴离子[PW12O40]3-构筑的一维超分子双链穿插于Pseudo-Keggin簇阴离子[PW12O40]3-二维超分子层的规则的菱形孔道中,形成新奇的三维超分子结构。
By the hydrothermal synthesis of a synthesis of a classic double-anion Keggin and pseudo-Keggin, 4,4’-bipy organic templates together to build a novel three-dimensional structure of the molecular structure (4,4’-bipy) 8H9 [ PW12O40] 2 [PW12O40] · 11H2O. The results of single crystal X-ray diffraction analysis showed that the compound belongs to the monoclinic system P1-space group with a = 1.1843 ) nm, b = 1.9218 (2) nm, c = 2.1036 (2) nm, α = 63.3420 (10) °, β = 74.148 (2) °, γ = 79.721 (2) °. The one-dimensional supramolecular double-stranded chain composed of Keggin cluster anion [PW12O40] 3- interweaves into the regular rhombic pore of the 3-dimensional supramolecular layer of Pseudo-Keggin cluster anion [PW12O40] to form a novel three-dimensional supramolecular structure.
