Materials Data on VOF3 by Materials Project

Abstract

VOF3 crystallizes in the tetragonal P-42_1m space group. The structure is one-dimensional and consists of two VOF3 ribbons oriented in the (0, 0, 1) direction. V5+ is bonded in a 6-coordinate geometry to two equivalent O2- and four F1- atoms. There are one shorter (1.62 Å) and one longer (2.41 Å) V–O bond lengths. There is two shorter (1.75 Å) and two longer (1.99 Å) V–F bond length. O2- is bonded in a distorted single-bond geometry to two equivalent V5+ atoms. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a water-like geometry to two equivalent V5+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one V5+ atom.
