Abstract
Fe2OF3 is zeta iron carbide-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are six inequivalent Fe+2.50+ sites. In the first Fe+2.50+ site, Fe+2.50+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that share corners with eight FeO2F4 octahedra and edges with two FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 47–54°. The Fe–O bond length is 2.05 Å. There are four shorter (2.11 Å) and one longer (2.18 Å) Fe–F bond lengths. In the second Fe+2.50+ site, Fe+2.50+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that share corners with eight equivalent FeO2F4 octahedra and edges with two equivalent FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 47–53°. The Fe–O bond length is 2.05 Å. There are four shorter (2.11 Å) and one longer (2.18 Å) Fe–F bond lengths. In the third Fe+2.50+ site, Fe+2.50+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that share corners with eight FeO2F4 octahedra and edges with two FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 44–58°. The Fe–O bond length is 2.05 Å. There are a spread ofmore »

There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three Fe+2.50+ atoms.
