摘要
利用高分辨率x射线粉末衍射数据对CrVMoO7的结构进行了细化。三斜晶胞(空间群P1¯)= 5.531 (1),b = 6.585 (1) a, c = 7.864(1),α= 96.143(6)°,β= 89.847(6)°和γ= 101.942(6)°。两步细化在第一步(模式匹配)和第二步(结构细化)中也产生Rp=8.7%。该化合物的晶体结构与FeVMoO7是同型的。在键价概念和有效配位数的框架内讨论了配位多面体的畸变。
The structure of CrVMoO7 has been refined from high-resolution X-ray powder diffraction data. The unit cell is triclinic (space group P1¯) with a=5.531(1)Å, b=6.585(1)Å, c=7.864(1)Å, α=96.143(6)°, β=89.847(6)° and γ=101.942(6)°. A two-step refinement yields Rp=8.7% in the first step (pattern matching) and in the second step (structure refinement)as well. The crystal structure of the compound is isotypic to FeVMoO7. The distortion of the coordination polyhedra has been discussed within the framework of the bond valence concept and effective coordination numbers.
