Title: Materials Data on Fe3OF5 by Materials Project

Abstract

Fe3OF5 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Fe+2.33+ sites. In the first Fe+2.33+ site, Fe+2.33+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with eight FeO2F4 octahedra and edges with two equivalent FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 47–57°. There are two shorter (2.08 Å) and four longer (2.11 Å) Fe–F bond lengths. In the second Fe+2.33+ site, Fe+2.33+ is bonded to two equivalent O2- and four F1- atoms to form FeO2F4 octahedra that share corners with eight FeF6 octahedra and edges with two FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. Both Fe–O bond lengths are 1.92 Å. There are a spread of Fe–F bond distances ranging from 2.06–2.13 Å. In the third Fe+2.33+ site, Fe+2.33+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with eight FeF6 octahedra and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are a spread of Fe–F bond distances ranging from 2.03–2.19 Å. In the fourth Fe+2.33+ site, Fe+2.33+ is bonded to one O2- and five F1- atoms tomore » form FeOF5 octahedra that share corners with eight FeO2F4 octahedra and edges with two FeF6 octahedra. The corner-sharing octahedra tilt angles range from 44–57°. The Fe–O bond length is 2.04 Å. There are a spread of Fe–F bond distances ranging from 2.10–2.17 Å. O2- is bonded in a distorted trigonal planar geometry to three Fe+2.33+ atoms. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.33+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.33+ atoms. In the third F1- site, F1- is bonded in a trigonal planar geometry to three Fe+2.33+ atoms. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.33+ atoms.« less
