Li2SnGe crystallizes in the cubic F-43m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent Sn(1) atoms to form distorted corner-sharing LiSn4 tetrahedra. In the second Li site, Li(2) is bonded to four equivalent Ge(1) atoms to form distorted corner-sharing LiGe4 tetrahedra. Sn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a body-centered cubic geometry to four equivalent Li(2) and four equivalent Sn(1) atoms.
