Materials Data on Al2RhC4Cl7O4 by Materials Project
RhAl2Cl7(CO)4 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of eight formaldehyde molecules, two rhodium molecules, and two Al2Cl7 clusters. In each Al2Cl7 cluster, there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four Cl1- atoms to form corner-sharing AlCl4 tetrahedra. There are a spread of Al–Cl bond distances ranging from 2.12–2.30 Å. In the second Al3+ site, Al3+ is bonded to four Cl1- atoms to form corner-sharing AlCl4 tetrahedra. There are a spread of Al–Cl bond distances ranging from 2.13–2.26 Å. There are seven inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom. In the second Cl1- site, Cl1- is bonded in a bent 120 degrees geometry to two Al3+ atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom. In the seventh Cl1- site, Cl1- is bonded in a single-bond geometry to one Al3+ atom.
