Mg3Li is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Li(1) is bonded in a body-centered cubic geometry to eight equivalent Mg(2) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to eight equivalent Mg(2) atoms. In the second Mg site, Mg(2) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Mg(1) atoms.
