The structure described by LiMg crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a body-centered cubic geometry to two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. In the second Li site, Li(2) is bonded in a distorted body-centered cubic geometry to two equivalent Li(3), two equivalent Mg(3), and four equivalent Mg(1) atoms. In the third Li site, Li(3) is bonded in a distorted body-centered cubic geometry to two equivalent Li(2), two equivalent Mg(3), and four equivalent Mg(2) atoms. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to two equivalent Li(1) and four equivalent Li(2) atoms. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to two equivalent Li(1) and four equivalent Li(3) atoms. In the third Mg site, Mg(3) is bonded in a body-centered cubic geometry to two equivalent Li(2), two equivalent Li(3), and four equivalent Li(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
