LiVF4 is beta Vanadium nitride-derived structured and crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with six equivalent VF6 octahedra, an edgeedge with one VF6 octahedra, and edges with two equivalent LiF6 octahedra. The corner-sharing octahedra tilt angles range from 42–56°. There are a spread of Li–F bond distances ranging from 2.00–2.11 Å. V3+ is bonded to six F1- atoms to form VF6 octahedra that share corners with four equivalent VF6 octahedra, corners with six equivalent LiF6 octahedra, and an edgeedge with one LiF6 octahedra. The corner-sharing octahedra tilt angles range from 42–56°. There are a spread of V–F bond distances ranging from 1.92–2.06 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent V3+ atoms. In the second F1- site, F1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one V3+ atom.
