Title: Materials Data on Fe2OF3 by Materials Project

Abstract

Fe2OF3 is zeta iron carbide-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are ten inequivalent Fe+2.50+ sites. In the first Fe+2.50+ site, Fe+2.50+ is bonded to two O2- and four F1- atoms to form FeO2F4 octahedra that share corners with eight FeO2F4 octahedra and edges with two FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 40–59°. There is one shorter (1.96 Å) and one longer (1.98 Å) Fe–O bond length. There are a spread of Fe–F bond distances ranging from 2.03–2.09 Å. In the second Fe+2.50+ site, Fe+2.50+ is bonded to two O2- and four F1- atoms to form a mixture of corner and edge-sharing FeO2F4 octahedra.
