Materials Data on Fe4O3F5 by Materials Project
Abstract
Fe4O3F5 is zeta iron carbide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Fe+2.75+ sites. In the first Fe+2.75+ site, Fe+2.75+ is bonded to three O2- and three F1- atoms to form FeO3F3 octahedra that share corners with eight FeO2F4 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 43–54°. There are a spread of Fe–O bond distances ranging from 1.92–2.02 Å. There are two shorter (2.12 Å) and one longer (2.17 Å) Fe–F bond lengths. 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 eight FeO2F4 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 47–55°. 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 2.13–2.20 Å. In the third Fe+2.75+ site, Fe+2.75+ is bonded to three O2- and three F1- atoms to form a mixture of edge and corner-sharing FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 45–52°. There are a spread of Fe–O bond distances rangingmore »
