Materials Data on LiLa(WO4)2 by Materials Project

Abstract

LiLa(WO4)2 is Zircon-derived structured and crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Li1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.51 Å) and four longer (2.55 Å) Li–O bond lengths. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.50 Å) and four longer (2.52 Å) La–O bond lengths. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All W–O bond lengths are 1.82 Å. In the second W6+ site, W6+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All W–O bond lengths are 1.83 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one La3+, and one W6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one La3+, and one W6+ atom.
