Rh(CO)4Al2Cl7 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Al2Cl7 clusters and two Rh(CO)4 clusters. In each Al2Cl7 cluster, there are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one Cl(2), one Cl(3), one Cl(4), and one Cl(7) atom to form corner-sharing AlCl4 tetrahedra. In the second Al site, Al(2) is bonded to one Cl(1), one Cl(2), one Cl(5), and one Cl(6) atom to form corner-sharing AlCl4 tetrahedra. There are seven inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Al(2) atom. In the second Cl site, Cl(2) is bonded in a bent 120 degrees geometry to one Al(1) and one Al(2) atom.
