Abstract: 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 -stacking is in a tail-to-tail fashion with an intermolecular distance of 3.26 Å. The molecule also exhibits intramolecular C-HCl and C-HO hydrogen bonds.
