Materials Data on V3(O2F)2 by Materials Project
Abstract
V3(O2F)2 is zeta iron carbide-derived structured and crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. there are three inequivalent V+3.33+ sites. In the first V+3.33+ site, V+3.33+ is bonded to four O2- and two equivalent F1- atoms to form a mixture of edge and corner-sharing VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 47–53°. There are a spread of V–O bond distances ranging from 1.87–1.93 Å. Both V–F bond lengths are 2.12 Å. In the second V+3.33+ site, V+3.33+ is bonded to four O2- and two F1- atoms to form a mixture of edge and corner-sharing VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 47–51°. There are two shorter (1.98 Å) and two longer (2.04 Å) V–O bond lengths. There are one shorter (2.09 Å) and one longer (2.11 Å) V–F bond lengths. In the third V+3.33+ site, V+3.33+ is bonded to four O2- and two equivalent F1- atoms to form a mixture of edge and corner-sharing VO4F2 octahedra. The corner-sharing octahedra tilt angles range from 47–53°. There are a spread of V–O bond distances ranging from 1.94–2.01 Å. Both V–F bond lengths are 2.11 Å. There are four inequivalent O2- sites.
