LiMgSb is half-Heusler structured and crystallizes in the cubic F-43m space group. Li(1) is bonded to four equivalent Sb(1) atoms to form LiSb4 tetrahedra that share corners with four equivalent Mg(1)Sb4 tetrahedra, corners with twelve equivalent Li(1)Sb4 tetrahedra, and edges with six equivalent Mg(1)Sb4 tetrahedra. Mg(1) is bonded to four equivalent Sb(1) atoms to form distorted MgSb4 tetrahedra that share corners with four equivalent Li(1)Sb4 tetrahedra, corners with twelve equivalent Mg(1)Sb4 tetrahedra, and edges with six equivalent Li(1)Sb4 tetrahedra. Sb(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Mg(1) atoms.
