InAlB is half-Heusler structured and crystallizes in the cubic F-43m space group. In(1) is bonded to four equivalent Al(1) atoms to form InAl4 tetrahedra that share corners with four equivalent B(1)Al4 tetrahedra, corners with twelve equivalent In(1)Al4 tetrahedra, and edges with six equivalent B(1)Al4 tetrahedra. Al(1) is bonded in a body-centered cubic geometry to four equivalent In(1) and four equivalent B(1) atoms. B(1) is bonded to four equivalent Al(1) atoms to form BAl4 tetrahedra that share corners with four equivalent In(1)Al4 tetrahedra, corners with twelve equivalent B(1)Al4 tetrahedra, and edges with six equivalent In(1)Al4 tetrahedra.
