Abstract
FeOF is beta Vanadium nitride-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to five O2- and one F1- atom to form FeO5F octahedra that share corners with eight FeO3F3 octahedra and edges with two equivalent FeO5F octahedra. The corner-sharing octahedra tilt angles range from 50–55°. There is one shorter (1.95 Å) and four longer (2.00 Å) Fe–O bond length. The Fe–F bond length is 2.31 Å. In the second Fe3+ site, Fe3+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that share corners with eight FeO3F3 octahedra and edges with two equivalent FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 45–52°. The Fe–O bond length is 1.80 Å. There are a spread of Fe–F bond distances ranging from 1.92–1.99 Å. In the third Fe3+ site, Fe3+ is bonded to three O2- and three F1- atoms to form FeO3F3 octahedra that share corners with eight FeO5F octahedra and edges with two equivalent FeO3F3 octahedra. The corner-sharing octahedra tilt angles range from 45–55°. There is one shorter (1.81 Å) and two longer (1.88 Å) Fe–O bondmore »
