Materials Data on Li2SnF6 by Materials Project
Li2SnF6 is beta Vanadium nitride-derived structured and crystallizes in the trigonal P-31m space group. The structure is three-dimensional. Li1+ is bonded to six equivalent F1- atoms to form LiF6 octahedra that share corners with six equivalent SnF6 octahedra and edges with three equivalent LiF6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Li–F bond lengths are 2.05 Å. Sn4+ is bonded to six equivalent F1- atoms to form SnF6 octahedra that share corners with twelve equivalent LiF6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Sn–F bond lengths are 2.01 Å. F1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one Sn4+ atom.
