AgAlSb2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgAlSb2 clusters. Ag(1) is bonded in a single-bond geometry to one Al(1) atom. The Ag(1)-Al(1) bond length is 0.05 Å. Al(1) is bonded in a single-bond geometry to one Ag(1) and two equivalent Sb(1) atoms. Both Al(1)-Sb(1) bond lengths are 2.02 Å. Sb(1) is bonded in a distorted single-bond geometry to one Al(1) atom.
