The compound described by Li2MgTl 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 14-coordinate geometry to four equivalent Li(2), four equivalent Mg(1), and six equivalent Tl(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Li(1) and four equivalent Tl(1) atoms to form distorted edge-sharing LiLi4Tl4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Tl(1) atoms. Tl(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(2), six equivalent Li(1), and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
