Title: Materials Data on Fe6O7F5 by Materials Project

Abstract

Fe6O7F5 is Hydrophilite-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to three O and three F atoms to form FeO3F3 octahedra that share corners with eight FeO4F2 octahedra and edges with two FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. There are a spread of Fe–O bond distances ranging from 1.91–2.00 Å. There are a spread of Fe–F bond distances ranging from 2.03–2.08 Å. In the second Fe site, Fe is bonded to three O and three F atoms to form FeO3F3 octahedra that share corners with eight equivalent FeO4F2 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There is one shorter (1.91 Å) and two longer (1.98 Å) Fe–O bond length. There are two shorter (2.07 Å) and one longer (2.08 Å) Fe–F bond lengths. In the third Fe site, Fe is bonded to four O and two F atoms to form FeO4F2 octahedra that share corners with eight FeO3F3 octahedra and edges with two FeO4F2 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There are a spreadmore » of Fe–O bond distances ranging from 1.96–2.01 Å. There are one shorter (2.13 Å) and one longer (2.35 Å) Fe–F bond lengths. In the fourth Fe site, Fe is bonded to four O and two equivalent F atoms to form FeO4F2 octahedra that share corners with eight equivalent FeO3F3 octahedra and edges with two equivalent FeO4F2 octahedra. The corner-sharing octahedra tilt angles range from 44–52°. All Fe–O bond lengths are 1.91 Å. Both Fe–F bond lengths are 2.16 Å. There are four inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to three Fe atoms. In the second O site, O is bonded in a distorted trigonal planar geometry to three Fe atoms. In the third O site, O is bonded in a trigonal planar geometry to three Fe atoms. In the fourth O site, O is bonded in a distorted trigonal planar geometry to three Fe atoms. There are three inequivalent F sites. In the first F site, F is bonded in a 3-coordinate geometry to three Fe atoms. In the second F site, F is bonded in a distorted trigonal planar geometry to three Fe atoms. In the third F site, F is bonded in a distorted trigonal planar geometry to three Fe atoms.« less
