Materials Data on Fe3OF5 by Materials Project
Fe3OF5 is zeta iron carbide-derived structured and crystallizes in the orthorhombic Cmmm 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 FeF6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are two shorter (2.03 Å) and four longer (2.13 Å) Fe–F bond lengths. In the second Fe+2.33+ site, Fe+2.33+ is bonded to two equivalent O2- and four equivalent F1- atoms to form FeO2F4 octahedra that share corners with eight FeF6 octahedra and edges with two equivalent FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 48–56°. Both Fe–O bond lengths are 2.09 Å. All Fe–F bond lengths are 2.12 Å. In the third Fe+2.33+ site, Fe+2.33+ is bonded to two equivalent O2- and four F1- atoms to form a mixture of edge and corner-sharing FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. Both Fe–O bond lengths are 1.91 Å. There are two shorter (2.03 Å) and two longer (2.20 Å) Fe–F bond lengths. In the fourth Fe+2.33+ site, Fe+2.33+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing FeF6 octahedra. The corner-sharing octahedra tilt angles range from 46–49°. There are a spread of Fe–F bond distances ranging from 2.04–2.14 Å. O2- is bonded in a 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 3-coordinate 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.
