The crystal structure described by 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. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Al(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Al(1) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Al(2) atom. In the sixth Cl site, Cl(6) is bonded in a single-bond geometry to one Al(2) atom. In the seventh Cl site, Cl(7) is bonded in a single-bond geometry to one Al(1) atom. In one of the Rh(CO)4 clusters, Rh(1) is bonded in a square co-planar geometry to two equivalent C(3) and two equivalent C(4) atoms. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted linear geometry to one Rh(1) and one O(3) atom. In the second C site, C(4) is bonded in a distorted linear geometry to one Rh(1) and one O(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(4) atom. In the second O site, O(3) is bonded in a single-bond geometry to one C(3) atom. In one of the Rh(CO)4 clusters, Rh(2) is bonded in a square co-planar geometry to two equivalent C(1) and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Rh(2) and one O(2,4) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Rh(2) and one O(2,4) atom. O(2,4) is bonded in a single-bond geometry to one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
