Abstract
VOF is beta Vanadium nitride-derived structured and crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are five inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to two O2- and four F1- atoms to form VO2F4 octahedra that share corners with eight VO3F3 octahedra and edges with two equivalent VO2F4 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There is one shorter (1.93 Å) and one longer (1.94 Å) V–O bond length. All V–F bond lengths are 2.07 Å. In the second V3+ site, V3+ is bonded to four equivalent O2- and two equivalent F1- atoms to form VO4F2 octahedra that share corners with eight equivalent VO3F3 octahedra and edges with two equivalent VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 48–50°. All V–O bond lengths are 2.02 Å. Both V–F bond lengths are 2.09 Å. In the third V3+ site, V3+ is bonded to two equivalent O2- and four equivalent F1- atoms to form VO2F4 octahedra that share corners with eight equivalent VO4F2 octahedra and edges with two equivalent VO2F4 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. Both V–O bond lengths are 1.94 Å. All V–F bond lengths aremore »
