The crystal and molecular structure of oxovanadium(V) orthophosphate dihydrate, VOPO₄,2H₂O

Abstract

The structure of a tetragonal crystal of the title compound was determined by X-ray diffraction. The space group was found to be P4/nmm with a 6.202(2) and c 7.410(1) Å and Z 2. The structure consists of infinite sheets of distorted VO₆ octahedra and PO₄ tetrahedra linked by shared oxygen atoms. Shared water molecules link these sheets together. A short V-O(4) bond, 1.567(5) Å, indicates the presence of the cation VO³⁺.
