La Al Al W
LaWAl2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 2-coordinate geometry to one W(1) and one Al(2) atom. The La(1)-W(1) bond length is 3.33 Å. The La(1)-Al(2) bond length is 2.43 Å. W(1) is bonded in a single-bond geometry to one La(1) and one Al(1) atom. The W(1)-Al(1) bond length is 1.25 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one W(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 2.21 Å. In the second Al site, Al(2) is bonded in a 6-coordinate geometry to one La(1), one Al(1), and four equivalent Al(2) atoms. All Al(2)-Al(2) bond lengths are 2.93 Å.
