Materials Data on Fe4OF7 by Materials Project
Abstract
Fe4OF7 is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Fe+2.25+ sites. In the first Fe+2.25+ site, Fe+2.25+ is bonded to six F1- atoms to form FeF6 octahedra that share corners with eight FeF6 octahedra and edges with two FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 43–56°. There are a spread of Fe–F bond distances ranging from 2.03–2.16 Å. In the second Fe+2.25+ site, Fe+2.25+ is bonded to one O2- and five F1- atoms to form a mixture of edge and corner-sharing FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 38–57°. The Fe–O bond length is 2.07 Å. There are a spread of Fe–F bond distances ranging from 2.03–2.23 Å. In the third Fe+2.25+ site, Fe+2.25+ is bonded to one O2- and five F1- atoms to form a mixture of edge and corner-sharing FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 38–56°. The Fe–O bond length is 1.83 Å. There are a spread of Fe–F bond distances ranging from 2.00–2.17 Å. In the fourth Fe+2.25+ site, Fe+2.25+ is bonded to one O2- and five F1- atoms to form a mixture of edge and corner-sharing FeOF5 octahedra.more »
