Materials Data on Li2MgHg by Materials Project

Li2MgHg crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded in a 4-coordinate geometry to four equivalent Mg atoms. All Li–Mg bond lengths are 2.91 Å. In the second Li site, Li is bonded to four equivalent Hg atoms to form distorted corner-sharing LiHg4 tetrahedra. All Li–Hg bond lengths are 2.91 Å. Mg is bonded in a body-centered cubic geometry to four equivalent Li and four equivalent Hg atoms. All Mg–Hg bond lengths are 2.91 Å. Hg is bonded in a body-centered cubic geometry to four equivalent Li and four equivalent Mg atoms.
