Carbonyl(5-chloroquinolin-8-olato-k² N,O)[tris-(4-chlorophenyl) phosphine-kP]rhodium(I)

In the title compound, [Rh(C9H7ClNO)(C18H12Cl3P)(CO)], the phosphine ligand is trans to the N atom of the quinolinolate ligand. This indicates that changes in the electronic properties of the quinolinolate backbone have a negligible influence on the phosphine substitution. Important geometrical parameters are the quinolinolate bite angle of 80.15 (9)° and the Rh - P bond distance of 2.2478 (9) Å, the effective cone angle (E) for the phosphine ligand being 165°. Quinoline ligand-to-ligand π-stacking is in a tail-to-tail fashion with an inter-molecular distance of 3.26 Å. The molecule also exhibits intramolecular C - H⋯Cl and C - H⋯O hydrogen bonds.
