LiAlSi is half-Heusler structured and crystallizes in the cubic F-43m space group. Li(1) is bonded to six equivalent Al(1) and four equivalent Si(1) atoms to form a mixture of distorted face and corner-sharing LiAl6Si4 tetrahedra. Al(1) is bonded in a 10-coordinate geometry to six equivalent Li(1) and four equivalent Si(1) atoms. Si(1) is bonded in a body-centered cubic geometry to four equivalent Li(1) and four equivalent Al(1) atoms.
