SmAuAl crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one SmAuAl cluster. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a distorted single-bond geometry to one Au(2) and one Al(2) atom. The Sm(1)-Au(2) bond length is 2.58 Å. The Sm(1)-Al(2) bond length is 1.33 Å. In the second Sm site, Sm(2) is bonded in a 2-coordinate geometry to one Au(2) and one Al(2) atom. The Sm(2)-Au(2) bond length is 2.61 Å. The Sm(2)-Al(2) bond length is 1.59 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 2-coordinate geometry to one Al(1) and one Al(2) atom. The Au(1)-Al(1) bond length is 1.34 Å. The Au(1)-Al(2) bond length is 1.58 Å. In the second Au site, Au(2) is bonded in a 2-coordinate geometry to one Sm(1) and one Sm(2) atom. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Au(1) atom. In the second Al site, Al(2) is bonded in a 3-coordinate geometry to one Sm(1), one Sm(2), and one Au(1) atom.
