Carbon-yl[4-(2,3-dimethyl-phenyl-amino)pent-3-en-2-onato-κN,O](triphenyl-phosphine-κP)rhodium(I).

In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)], the coordination geometry of the Rh(I) atom is square-planar, formed by the coordinating N and O atoms of the bidentate enaminoketonate ligand, one C atom from the carbonyl group and a P atom from triphenyl-phosphine. The complex displays a 0.591†(3):0.409†(3) ratio disorder of the phenyl unit of the monoanionic N,O-bidentate ligand. Intra-molecular hydrogen bonding is observed between a C-H group of the triphenyl-phosphine unit and the O atom of the enamino-ketonate ligand.
