Al Al Ir Cl
IrAl2Cl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrAl2Cl cluster. Ir(1) is bonded in a single-bond geometry to one Al(1) and one Cl(1) atom. The Ir(1)-Al(1) bond length is 0.74 Å. The Ir(1)-Cl(1) bond length is 2.42 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted single-bond geometry to one Ir(1), one Al(2), and one Cl(1) atom. The Al(1)-Al(2) bond length is 0.74 Å. The Al(1)-Cl(1) bond length is 2.41 Å. In the second Al site, Al(2) is bonded in a 1-coordinate geometry to one Al(1) and one Cl(1) atom. The Al(2)-Cl(1) bond length is 2.42 Å. Cl(1) is bonded in a 3-coordinate geometry to one Ir(1), one Al(1), and one Al(2) atom.
