The structure described by AlFeY crystallizes in the orthorhombic Imma space group. Y(1) is bonded in a 12-coordinate geometry to six equivalent Fe(1) and six equivalent Al(1) atoms. Fe(1) is bonded to six equivalent Y(1), two equivalent Fe(1), and four equivalent Al(1) atoms to form FeY6Al4Fe2 cuboctahedra that share corners with eight equivalent Al(1)Y6Al2Fe4 cuboctahedra, corners with ten equivalent Fe(1)Y6Al4Fe2 cuboctahedra, edges with six equivalent Fe(1)Y6Al4Fe2 cuboctahedra, faces with six equivalent Fe(1)Y6Al4Fe2 cuboctahedra, and faces with twelve equivalent Al(1)Y6Al2Fe4 cuboctahedra.
