Materials Data on LiSmAlF6 by Materials Project
LiSmAlF6 crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. Li1+ is bonded to six equivalent F1- atoms to form LiF6 octahedra that share edges with three equivalent AlF6 octahedra. All Li–F bond lengths are 2.02 Å. Sm2+ is bonded in a 6-coordinate geometry to six equivalent F1- atoms. All Sm–F bond lengths are 2.43 Å. Al3+ is bonded to six equivalent F1- atoms to form AlF6 octahedra that share edges with three equivalent LiF6 octahedra. All Al–F bond lengths are 1.83 Å. F1- is bonded in a 3-coordinate geometry to one Li1+, one Sm2+, and one Al3+ atom.
