Title: 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 FeOF5 octahedra and edges with two FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 42–55°. There are a spread of Fe–O bond distances ranging from 1.90–2.05 Å. There are a spread of Fe–F bond distances ranging from 2.00–2.25 Å. In the second 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 FeOF5 octahedra and edges with two FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 34–59°. All Fe–O bond lengths are 1.94 Å. There are a spread of Fe–F bond distances ranging from 2.10–2.27 Å. In the third 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 FeOF5 octahedra and edges with two FeO3F3 octahedra.
