The material structure described by Li2MgAg 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 Ag(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Li(1) and four equivalent Ag(1) atoms to form distorted edge-sharing LiLi4Ag4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Ag(1) atoms. Ag(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 CIF card [CIF]
