Li2ZnSn 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 Zn(1) atoms to form distorted corner-sharing LiZn4 tetrahedra. Zn(1) is bonded in a body-centered cubic geometry to four equivalent Li(2) and four equivalent Sn(1) atoms. Sn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Zn(1) atoms.
