description: V3Cr3(WO8)2 is beta Vanadium nitride-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, an edgeedge with one WO6 octahedra, and edges with four CrO6 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are a spread of V–O bond distances ranging from 1.84–2.16 Å. In the second V5+ site, V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, an edgeedge with one WO6 octahedra, edges with two equivalent VO6 octahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of V–O bond distances ranging from 1.86–2.14 Å. In the third V5+ site, V5+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent WO6 octahedra, an edgeedge with one WO6 octahedra, edges with two equivalent VO6 octahedra, and edges with two equivalent CrO6 octahedra.
