Materials Data on Fe5(OF4)2 by Materials Project
Abstract
Fe5(OF4)2 is zeta iron carbide-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Fe+2.40+ sites. In the first Fe+2.40+ site, Fe+2.40+ 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 48–59°. The Fe–O bond length is 2.04 Å. There are a spread of Fe–F bond distances ranging from 2.10–2.21 Å. In the second Fe+2.40+ site, Fe+2.40+ is bonded to two equivalent O2- and four F1- atoms to form a mixture of edge and corner-sharing FeO2F4 octahedra. The corner-sharing octahedra tilt angles range from 44–59°. Both Fe–O bond lengths are 2.00 Å. There are two shorter (2.21 Å) and two longer (2.24 Å) Fe–F bond lengths. In the third Fe+2.40+ site, Fe+2.40+ 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 43–51°. The Fe–O bond length is 1.84 Å. There are a spread of Fe–F bond distances ranging from 2.02–2.08 Å. O2- is bonded in a distorted trigonal planar geometry to three Fe+2.40+ atoms. There are four inequivalentmore »
