Rhodium acetylacetonate is the coordination complex with the formula Rh(O₂C₅H₇)₃, which is sometimes known as Rh(acac)₃. The molecule has D₃-symmetry. It is a yellow-orange solid that is soluble in organic solvents.

It is prepared from RhCl₃(H₂O)₃ and acetylacetone.[1] The complex has been resolved into individual enantiomers by separation of its adduct with dibenzoyltartaric acid.[2]
