Materials Data on Fe4O3F5 by Materials Project
Abstract
Fe4O3F5 is zeta iron carbide-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Fe+2.75+ sites. In the first 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 eight FeO2F4 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 49–53°. Both Fe–O bond lengths are 2.07 Å. There are two shorter (2.17 Å) and two longer (2.19 Å) Fe–F bond lengths. In the second 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 eight FeO2F4 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 40–53°. Both Fe–O bond lengths are 1.97 Å. There are two shorter (2.02 Å) and two longer (2.05 Å) Fe–F bond lengths. In the third Fe+2.75+ site, Fe+2.75+ is bonded to three O2- and three F1- atoms to form a mixture of distorted corner and edge-sharing FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 40–57°. There is two shorter (1.91 Å) and one longer (1.96 Å) Fe–O bond length. There aremore »
