Materials Data on Li2VOF3 by Materials Project
Abstract
Li2VOF3 crystallizes in the orthorhombic Pnc2 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to two equivalent O2- and four F1- atoms to form LiO2F4 octahedra that share corners with two equivalent VO2F4 octahedra and edges with three VO2F4 octahedra. The corner-sharing octahedral tilt angles are 55°. Both Li–O bond lengths are 2.19 Å. There are two shorter (2.04 Å) and two longer (2.09 Å) Li–F bond lengths. In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.91–2.29 Å. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to two equivalent O2- and four F1- atoms. Both Li–O bond lengths are 1.93 Å. There are two shorter (2.34 Å) and two longer (2.58 Å) Li–F bond lengths. In the fourth Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.90–2.34 Å. There are two inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to two equivalent O2- and four F1- atoms tomore »

O2- is bonded to two Li1+ and two V3+ atoms to form a mixture of distorted corner and edge-sharing OLi2V2 trigonal pyramids. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to two Li1+ and two V3+ atoms. In the second F1- site, F1- is bonded in a 5-coordinate geometry to four Li1+ and one V3+ atom.
