Materials Data on Fe3(OF2)2 by Materials Project
Abstract
Fe3(OF2)2 is zeta iron carbide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ 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 43–57°. There is one shorter (1.91 Å) and one longer (1.92 Å) Fe–O bond length. There are a spread of Fe–F bond distances ranging from 2.04–2.14 Å. In the second Fe+2.67+ site, Fe+2.67+ 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 48–57°. Both Fe–O bond lengths are 2.04 Å. There are two shorter (2.15 Å) and two longer (2.21 Å) Fe–F bond lengths. O2- is bonded in a distorted trigonal planar geometry to three Fe+2.67+ atoms. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to three Fe+2.67+ atoms. In the second F1- site, F1- is bonded in a trigonal planar geometry to three Fe+2.67+ atoms.
