Materials Data on Li2GeF6 by Materials Project
Li2GeF6 is beta Vanadium nitride-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 four equivalent LiF6 octahedra, corners with four equivalent GeF6 octahedra, an edgeedge with one LiF6 octahedra, and an edgeedge with one GeF6 octahedra. The corner-sharing octahedra tilt angles range from 44–57°. There are a spread of Li–F bond distances ranging from 2.05–2.10 Å. Ge4+ is bonded to six F1- atoms to form GeF6 octahedra that share corners with eight equivalent LiF6 octahedra and edges with two equivalent LiF6 octahedra. The corner-sharing octahedra tilt angles range from 44–45°. There is four shorter (1.83 Å) and two longer (1.84 Å) Ge–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one Ge4+ atom. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one Ge4+ atom.
