Title: Materials Data on Fe4OF7 by Materials Project

Abstract

Fe4OF7 is Hydrophilite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Fe+2.25+ sites. In the first Fe+2.25+ site, Fe+2.25+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that share corners with eight FeF6 octahedra and edges with two equivalent FeOF5 octahedra.
