The compound described by LiMgN is half-Heusler structured and crystallizes in the cubic F-43m space group. Li(1) is bonded to four equivalent N(1) atoms to form LiN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra, corners with twelve equivalent Li(1)N4 tetrahedra, and edges with six equivalent Mg(1)N4 tetrahedra. Mg(1) is bonded to four equivalent N(1) atoms to form MgN4 tetrahedra that share corners with four equivalent Li(1)N4 tetrahedra, corners with twelve equivalent Mg(1)N4 tetrahedra, and edges with six equivalent Li(1)N4 tetrahedra. N(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
