The material structure described by Li2MgPb 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 Pb(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Li(1) and four equivalent Pb(1) atoms to form distorted edge-sharing LiLi4Pb4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Pb(1) atoms. Pb(1) is bonded in a 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]
