Al is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form a mixture of corner, face, and edge-sharing AlAl12 cuboctahedra. In the second Al site, Al(2) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form a mixture of corner, face, and edge-sharing AlAl12 cuboctahedra.

In the first Al site, Al(1) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form a mixture of corner, face, and edge-sharing AlAl12 cuboctahedra. All Al(1)-Al(1) bond lengths are 2.83 Å. All Al(1)-Al(2) bond lengths are 2.82 Å. In the second Al site, Al(2) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form a mixture of corner, face, and edge-sharing AlAl12 cuboctahedra. All Al(2)-Al(2) bond lengths are 2.83 Å.
