The compound described by NdLaAl6 crystallizes in the hexagonal P-6m2 space group. Nd(1) is bonded in a 12-coordinate geometry to six equivalent Al(1) and six equivalent Al(2) atoms. La(1) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form a mixture of distorted corner and face-sharing LaAl12 cuboctahedra. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to two equivalent Nd(1), two equivalent La(1), two equivalent Al(1), and four equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to two equivalent Nd(1), two equivalent La(1), two equivalent Al(2), and four equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
