title: Materials Data on V6O7F5 by Materials Project

description: V6O7F5 is beta Vanadium nitride-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent V+3.17+ sites. In the first V+3.17+ site, V+3.17+ is bonded to four O2- and two F1- atoms to form VO4F2 octahedra that share corners with eight VO2F4 octahedra and edges with two VO5F octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are one shorter (2.00 Å) and three longer (2.01 Å) V–O bond lengths. There are one shorter (2.11 Å) and one longer (2.12 Å) V–F bond lengths. In the second V+3.17+ site, V+3.17+ is bonded to five O2- and one F1- atom to form distorted VO5F octahedra that share corners with eight VO2F4 octahedra and edges with two VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are a spread of V–O bond distances ranging from 1.81–1.99 Å. The V–F bond length is 2.37 Å. In the third V+3.17+ site, V+3.17+ is bonded to four O2- and two F1- atoms to form VO4F2 octahedra that share corners with eight VO2F4 octahedra and edges with two VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 47–53°. All V–O bond lengths are 2.01 Å. There are one shorter (2.11 Å) and one longer (2.12 Å) V–F bond lengths. In the fourth V+3.17+ site, V+3.17+ is bonded to two O2- and four F1- atoms to form VO2F4 octahedra that share corners with eight VO4F2 octahedra and edges with two VO3F3 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There is one shorter (1.92 Å) and one longer (1.95 Å) V–O bond length. There are a spread of V–F bond distances ranging from 2.05–2.08 Å. In the fifth V+3.17+ site, V+3.17+ is bonded to three O2- and three F1- atoms to form VO3F3 octahedra that share corners with eight VO4F2 octahedra and edges with two VO2F4 octahedra. The corner-sharing octahedra tilt angles range from 47–52°. There are a spread of V–O bond distances ranging from 1.93–2.02 Å. There are a spread of V–F bond distances ranging from 2.06–2.10 Å. In the sixth V+3.17+ site, V+3.17+ is bonded to three O2- and three F1- atoms to form VO3F3 octahedra that share corners with eight VO4F2 octahedra and edges with two VO2F4 octahedra. The corner-sharing octahedra tilt angles range from 47–53°. There are a spread of V–O bond distances ranging from 1.95–2.02 Å. There are a spread of V–F bond distances ranging from 2.05–2.08 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms. In the third F1- site, F1- is bonded in a 3-coordinate geometry to three V+3.17+ atoms. In the fourth F1- site, F1- is bonded in a 3-coordinate geometry to three V+3.17+ atoms. In the fifth F1- site, F1- is bonded in a distorted trigonal planar geometry to three V+3.17+ atoms.
