The material structure described by LiMgAs is half-Heusler structured and crystallizes in the cubic F-43m space group. Li(1) is bonded to four equivalent As(1) atoms to form distorted LiAs4 tetrahedra that share corners with four equivalent Mg(1)As4 tetrahedra, corners with twelve equivalent Li(1)As4 tetrahedra, and edges with six equivalent Mg(1)As4 tetrahedra. Mg(1) is bonded to four equivalent As(1) atoms to form distorted MgAs4 tetrahedra that share corners with four equivalent Li(1)As4 tetrahedra, corners with twelve equivalent Mg(1)As4 tetrahedra, and edges with six equivalent Li(1)As4 tetrahedra. As(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 file [CIF]
