Materials Data on LiBiF4 by Materials Project
BiLiF4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Li1+ is bonded in a tetrahedral geometry to four equivalent F1- atoms. All Li–F bond lengths are 1.94 Å. Bi3+ is bonded in a 8-coordinate geometry to eight equivalent F1- atoms. There are four shorter (2.36 Å) and four longer (2.42 Å) Bi–F bond lengths. F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent Bi3+ atoms.
