AlSiLa is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. La(1) is bonded to six Al(1,1) and six Si(1,1) atoms to form a mixture of edge and face-sharing LaAl6Si6 cuboctahedra. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted trigonal planar geometry to six equivalent La(1) and three Si(1,1) atoms. In the second Al site, Al(1) is bonded in a distorted trigonal planar geometry to six equivalent La(1) and three Si(1,1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted trigonal planar geometry to six equivalent La(1) and three Al(1,1) atoms. In the second Si site, Si(1) is bonded in a distorted trigonal planar geometry to six equivalent La(1) and three Al(1,1) atoms.

La(1) is bonded to six Al(1,1) and six Si(1,1) atoms to form a mixture of edge and face-sharing LaAl6Si6 cuboctahedra. There are two shorter (3.27 Å) and four longer (3.30 Å) La(1)-Al(1,1) bond lengths. There are two shorter (3.26 Å) and four longer (3.30 Å) La(1)-Si(1,1) bond lengths. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted trigonal planar geometry to six equivalent La(1) and three Si(1,1) atoms.
