description: V3PbP4O17 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent V4+ sites. In the first V4+ site, V4+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 8–14°. There are a spread of V–O bond distances ranging from 1.68–2.16 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. There are a spread of V–O bond distances ranging from 1.67–2.29 Å. In the third V4+ site, V4+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent VO6 octahedra and corners with four PO4 tetrahedra.
