AgSbAl2Sb is alpha carbon monoxide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgSb clusters and two Al2Sb clusters. In each AgSb cluster, Ag(1) is bonded in a single-bond geometry to one Sb(1) atom. The Ag(1)-Sb(1) bond length is 0.57 Å. Sb(1) is bonded in a single-bond geometry to one Ag(1) atom. In each Al2Sb cluster, Al(1) is bonded in a distorted single-bond geometry to one Sb(2) atom. The Al(1)-Sb(2) bond length is 0.17 Å. Sb(2) is bonded in a 2-coordinate geometry to two equivalent Al(1) atoms.
