Materials Data on Fe4O3F5 by Materials Project
Fe4O3F5 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Fe+2.75+ sites. In the first Fe+2.75+ site, Fe+2.75+ is bonded to two O2- and four F1- atoms to form distorted FeO2F4 octahedra that share corners with six FeO2F4 octahedra, a cornercorner with one FeO3F2 square pyramid, and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 48–57°. There is one shorter (1.84 Å) and one longer (1.97 Å) Fe–O bond length. There are a spread of Fe–F bond distances ranging from 2.01–2.31 Å. In the second Fe+2.75+ site, Fe+2.75+ is bonded to two O2- and four F1- atoms to form FeO2F4 octahedra that share corners with six FeO2F4 octahedra, corners with two equivalent FeO3F2 square pyramids, and edges with two equivalent FeO3F2 square pyramids. The corner-sharing octahedra tilt angles range from 48–57°. There are one shorter (2.04 Å) and one longer (2.06 Å) Fe–O bond lengths. There are a spread of Fe–F bond distances ranging from 2.09–2.21 Å. In the third Fe+2.75+ site, Fe+2.75+ is bonded to three O2- and two F1- atoms to form distorted FeO3F2 square pyramids that share corners with four FeO2F4 octahedra, corners with two equivalent FeO3F2 square pyramids, and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 40–56°. There are a spread of Fe–O bond distances ranging from 1.88–1.96 Å. There are one shorter (2.05 Å) and one longer (2.11 Å) Fe–F bond lengths. In the fourth Fe+2.75+ site, Fe+2.75+ is bonded to two equivalent O2- and four F1- atoms to form FeO2F4 octahedra that share corners with six FeO2F4 octahedra, a cornercorner with one FeO3F2 square pyramid, and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There is one shorter (1.93 Å) and one longer (1.95 Å) Fe–O bond length. There are a spread of Fe–F bond distances ranging from 2.03–2.06 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. In the third F1- site, F1- is bonded in a water-like geometry to two Fe+2.75+ atoms. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to three Fe+2.75+ atoms. In the fifth F1- site, F1- is bonded in a 3-coordinate geometry to three Fe+2.75+ atoms.
