LiV2F6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with eight equivalent VF6 octahedra and edges with two equivalent VF6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two shorter (2.06 Å) and four longer (2.09 Å) Li–F bond lengths. V+2.50+ is bonded to six F1- atoms to form VF6 octahedra that share corners with four equivalent LiF6 octahedra, corners with four equivalent VF6 octahedra, an edgeedge with one LiF6 octahedra, and an edgeedge with one VF6 octahedra. The corner-sharing octahedra tilt angles range from 49–50°. There are two shorter (2.03 Å) and four longer (2.05 Å) V–F bond lengths. 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 V+2.50+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent V+2.50+ atoms.
