The material structure described by AlLa3 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded in a 12-coordinate geometry to eight equivalent La(1) and four equivalent Al(1) atoms. Al(1) is bonded to twelve equivalent La(1) atoms to form a mixture of face and corner-sharing AlLa12 cuboctahedra. is represented by the CIF file [CIF]
