AgAl2Cl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgAl2Cl cluster. Ag(1) is bonded in a single-bond geometry to one Al(1), one Al(2), and one Cl(1) atom. The Ag(1)-Al(1) bond length is 1.01 Å. The Ag(1)-Al(2) bond length is 0.26 Å. The Ag(1)-Cl(1) bond length is 1.47 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to one Ag(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 1.01 Å. In the second Al site, Al(2) is bonded in a single-bond geometry to one Ag(1), one Al(1), and one Cl(1) atom. The Al(2)-Cl(1) bond length is 1.47 Å. Cl(1) is bonded in a 2-coordinate geometry to one Ag(1) and one Al(2) atom.
