The compound described by Li2MgSb crystallizes in the cubic F-43m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(2) and four equivalent Mg(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Li(1) and four equivalent Sb(1) atoms to form distorted edge-sharing LiLi4Sb4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Sb(1) atoms. Sb(1) is bonded in a body-centered cubic geometry to four equivalent Li(2) and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
