Materials Data on Li2NbF6 by Materials Project
Li2NbF6 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 NbF6 octahedra and edges with three equivalent LiF6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Li–F bond lengths are 2.05 Å. Nb4+ is bonded to six equivalent F1- atoms to form NbF6 octahedra that share corners with twelve equivalent LiF6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Nb–F bond lengths are 2.02 Å. F1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one Nb4+ atom.
