Li2MgCd 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 Cd(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Li(1) and four equivalent Cd(1) atoms to form distorted edge-sharing LiLi4Cd4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Cd(1) atoms. Cd(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.
