Abstract
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.
