Al5W crystallizes in the hexagonal P6_322 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to three equivalent Al(1), three equivalent Al(2), and six equivalent Al(3) atoms to form WAl12 cuboctahedra that share corners with three equivalent Al(2)Al9W3 cuboctahedra, corners with six equivalent W(1)Al12 cuboctahedra, corners with nine equivalent Al(1)Al9W3 cuboctahedra, edges with six equivalent W(1)Al12 cuboctahedra, faces with three equivalent Al(1)Al9W3 cuboctahedra, and faces with five equivalent Al(2)Al9W3 cuboctahedra. In the second W site, W(1) is bonded to three equivalent Al(1), three equivalent Al(2), and six equivalent Al(3) atoms to form WAl12 cuboctahedra that share corners with three equivalent Al(2)Al9W3 cuboctahedra, corners with six equivalent W(1)Al12 cuboctahedra, corners with nine equivalent Al(1)Al9W3 cuboctahedra, edges with six equivalent W(1)Al12 cuboctahedra, faces with three equivalent Al(1)Al9W3 cuboctahedra, and faces with five equivalent Al(2)Al9W3 cuboctahedra.
