AgAl2Sb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgAl2Sb clusters. Ag(1) is bonded in a distorted single-bond geometry to one Al(1) and one Sb(1) atom. The Ag(1)-Al(1) bond length is 1.97 Å. The Ag(1)-Sb(1) bond length is 0.55 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Ag(1) atom. In the second Al site, Al(2) is bonded in a single-bond geometry to one Sb(1) atom. The Al(2)-Sb(1) bond length is 2.52 Å. Sb(1) is bonded in a single-bond geometry to one Ag(1) and one Al(2) atom.
