【摘要】 采用水热合成法得到了一种具有纳米级微孔的氧簇化合物Kd(H2SiW12O38)·6H2O,经单晶衍射测定,晶体属于六方晶系,空间群为P62,晶胞参数为:a=19.0678(9)×10-10m,b=19.0678(9)×10-10m,c=12.5228(5)×10-10m;α=90°,β=90°,γ=120°,V=3943.1(3)×10-10m3,Z=3,Dc=3.811g/cm3,F(000)=3876,R1=0.0334,Rw=0.0887。氧簇化合物在c轴方向具有纳米级的微孔,孔径大约为1.1~1.2nm,同时在a轴和b轴方向上则具有较小的微孔,从而形成了三维的孔道结构。
【Abstract】 The title compound was synthesized under hydrothermal condition and its crystal structure was determinedby X-ray diffraction. It belonged to hexagonal system, space group P62, with α=19.0678(9)×10-10m, b=19.0678(9)×l0-10m, c=12.5228(5)×10-10m: α=90°, β=90°, γ=120°, Volume=3943.1(3)×10-10m3, Z=3, Dc=3.811 g/cm3, F(000)=3876, Rl=0.0334, Rw=0.0887. There was a nano-micropore along c axis, the diameter ofwhich was 1.1~1.2nm; at the same time along a axis and b axis there were two smaller pores.
