Materials Data on V3(PO4)2 by Materials Project
V3(PO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent V2+ sites. In the first V2+ site, V2+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with four PO4 tetrahedra, corners with four VO5 trigonal bipyramids, an edgeedge with one PO4 tetrahedra, and an edgeedge with one VO5 trigonal bipyramid. There are a spread of V–O bond distances ranging from 2.12–2.33 Å. In the second V2+ site, V2+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent VO6 octahedra, corners with three PO4 tetrahedra, a cornercorner with one VO5 trigonal bipyramid, an edgeedge with one PO4 tetrahedra, and an edgeedge with one VO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 42–62°. There are a spread of V–O bond distances ranging from 2.09–2.29 Å. In the third V2+ site, V2+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent VO6 octahedra, corners with five PO4 tetrahedra, a cornercorner with one VO5 trigonal bipyramid, and an edgeedge with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 57–68°. There are a spread of V–O bond distances ranging from 2.11–2.24 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one VO6 octahedra, corners with three VO5 trigonal bipyramids, an edgeedge with one VO6 octahedra, and an edgeedge with one VO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 32°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent VO6 octahedra and corners with five VO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 34–61°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent V2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two V2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two V2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two V2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two V2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two V2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two V2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two V2+ and one P5+ atom.
