Abstract: In the title compound, [Rh(C₁₃H₁₆NO)(C₁₈H₁₅P)(CO)]·0.5C₃H₆O, the Rh atom exhibits a square-planar coordination geometry, being coordinated by the N and O atoms of the bidentate -diketonato ligand, a P atom from the triphenylphosphine unit and a C atom from the carbonyl group. The asymmetric unit also contains a disordered half-molecule, lying about an inversion center, of the acetone solvate. Intermolecular C-HO hydrogen bonds are observed between a C-H group of the triphenylphosphine unit and a carbonyl O atom and between the methyl group of the enaminoketonato backbone and the solvent O atom. In addition, an intramolecular interaction is observed between a C-H group of the triphenylphosphine unit and the O atom of the enaminoketonato ligand.
