Materials Data on Li2SnGe by Materials Project
Li2SnGe 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 Sn atoms to form distorted corner-sharing LiSn4 tetrahedra. All Li–Sn bond lengths are 2.98 Å. In the second Li site, Li is bonded to four equivalent Ge atoms to form distorted corner-sharing LiGe4 tetrahedra. All Li–Ge bond lengths are 2.98 Å. Sn is bonded in a distorted body-centered cubic geometry to four equivalent Li and four equivalent Ge atoms. All Sn–Ge bond lengths are 2.98 Å. Ge is bonded in a body-centered cubic geometry to four equivalent Li and four equivalent Sn atoms.
