LiCaAs 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 LiAs4 tetrahedra that share corners with four equivalent Ca(1)As4 tetrahedra, corners with twelve equivalent Li(1)As4 tetrahedra, and edges with six equivalent Ca(1)As4 tetrahedra. Ca(1) is bonded to four equivalent As(1) atoms to form CaAs4 tetrahedra that share corners with four equivalent Li(1)As4 tetrahedra, corners with twelve equivalent Ca(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 Ca(1) atoms.
