title: Carbonyl[4-(2,6-dimethyl-phenyl-amino)pent-3-en-2-onato-κN,O](triphenyl-phosphine-κP)rhodium(I) acetone hemi-solvate.
abstract: In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)]·0.5C(3)H(6)O, the Rh atom exhibits a square-planar coordination geometry, being coordinated by the N and O atoms of the bidentate β-diketonato ligand, a P atom from the triphenyl-phosphine unit and a C atom from the carbonyl group. The asymmetric unit also contains a disordered half-mol-ecule, lying about an inversion center, of the acetone solvate. Inter-molecular C-H⋯O hydrogen bonds are observed between a C-H group of the triphenyl-phosphine unit and a carbonyl O atom and between the methyl group of the enamino-ketonato backbone and the solvent O atom. In addition, an intra-molecular inter-action is observed between a C-H group of the triphenyl-phosphine unit and the O atom of the enamino-ketonato ligand.
