Li2MgHg 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 4-coordinate geometry to four equivalent Mg(1) atoms. In the second Li site, Li(2) is bonded to four equivalent Hg(1) atoms to form distorted corner-sharing LiHg4 tetrahedra. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Hg(1) atoms. Hg(1) is bonded in a body-centered cubic geometry to four equivalent Li(2) and four equivalent Mg(1) atoms.
