Materials Data on Fe3(O2F)2 by Materials Project
Abstract
Fe3(O2F)2 is Hydrophilite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to four O and two equivalent F atoms to form FeO4F2 octahedra that share corners with eight FeO4F2 octahedra and edges with two equivalent FeO5F octahedra. The corner-sharing octahedra tilt angles range from 44–51°. There is two shorter (1.94 Å) and two longer (1.95 Å) Fe–O bond length. Both Fe–F bond lengths are 2.14 Å. In the second Fe site, Fe is bonded to five O and one F atom to form a mixture of distorted edge and corner-sharing FeO5F octahedra. The corner-sharing octahedra tilt angles range from 45–54°. There are a spread of Fe–O bond distances ranging from 1.96–2.00 Å. The Fe–F bond length is 2.50 Å. In the third Fe site, Fe is bonded to four O and two equivalent F atoms to form FeO4F2 octahedra that share corners with eight FeO4F2 octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There is two shorter (1.92 Å) and two longer (1.96 Å) Fe–O bond length. Both Fe–F bond lengths are 2.08more »
