LiMg crystallizes in the monoclinic C2/m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to two equivalent Li(2), two equivalent Mg(1), and two equivalent Mg(2) atoms. In the second Li site, Li(2) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Mg(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Li(2) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to four equivalent Li(1) atoms.

In the first Li site, Li(1) is bonded in a 4-coordinate geometry to two equivalent Li(2), two equivalent Mg(1), and two equivalent Mg(2) atoms. Both Li(1)-Li(2) bond lengths are 2.84 Å. Both Li(1)-Mg(1) bond lengths are 2.97 Å. Both Li(1)-Mg(2) bond lengths are 3.03 Å. In the second Li site, Li(2) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Mg(1) atoms. All Li(2)-Mg(1) bond lengths are 2.94 Å. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Li(2) atoms.
