Materials Data on Li2SnAu by Materials Project

Abstract

Li2AuSn crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to four equivalent Au atoms to form distorted corner-sharing LiAu4 tetrahedra. All Li–Au bond lengths are 2.84 Å. In the second Li site, Li is bonded to four equivalent Sn atoms to form distorted corner-sharing LiSn4 tetrahedra. All Li–Sn bond lengths are 2.84 Å. Au is bonded in a distorted body-centered cubic geometry to four equivalent Li and four equivalent Sn atoms. All Au–Sn bond lengths are 2.84 Å. Sn is bonded in a distorted body-centered cubic geometry to four equivalent Li and four equivalent Au atoms.
