以H4SiMo12O40.nH2O和[Cr3O(OOCC2H5)6(H2O)3]NO3.nH2O等为原料,合成了一例新颖的微孔化合物K2[Cr3O(OOCC2H5)6(H2O)3]2[SiMo12O40].1.5HAc.6H2O;利用X射线衍射仪、X射线光电子能谱仪、红外光谱仪及紫外光谱仪分析了产物的晶体结构和分子结构.结果表明,合成的化合物属于三斜晶系,P-1(2)空间群,晶胞参数为a=1.299 64(5)nm,b=1.299 64(5)nm,c=2.090 26(8)nm,α=76.406 0(10)°,β=74.126 0(10)°,γ=79.658 0(10)°,Z=2.就其分子结构而言,阴、阳离子通过K+离子的桥联作用形成一维链状结构,而相邻链之间通过氢键形成二维层状结构.
A novel microporous compound K2 [Cr3O (OOCC2H5) 6 (H2O) 3] 2 [SiMo12O40] was synthesized from H4SiMo12O40.nH2O and [Cr3O (OOCC2H5) 6 (H2O) 3] NO3.nH2O, .6H2O.The crystal structure and molecular structure of the product were analyzed by X-ray diffraction, X-ray photoelectron spectroscopy, infrared spectroscopy and UV spectroscopy.The results show that the synthesized compounds belong to the triclinic system P-1 (2) Group, the unit cell parameters are a = 1.299 64 (5) nm, b = 1.299 64 (5) nm, c = 2.090 26 (8) nm, α = 76.406 0 (10) °, , γ = 79.658 0 (10) °, Z = 2. In terms of its molecular structure, the anion and cation form a one-dimensional chain structure through the bridging action of K + ions, and the adjacent chains form a two-dimensional Layered structure.
