Carbonyl[4-(2,3-dimethylphenylamino)pent-3-en-2-onato-κ²N,O](triphenylphosphine-κP)rhodium(I)

Abstract

In the title compound, [Rh(C13H16NO)(C18H15P)(CO)], the coordination geometry of the RhI 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 triphenyl­phosphine. The complex displays a 0.591 (3):0.409 (3) ratio disorder of the phenyl unit of the monoanionic N,O-bidentate ligand. Intra­molecular hydrogen bonding is observed between a C—H group of the triphenyl­phosphine unit and the O atom of the enamino­ketonate ligand.

“…Two isomers are present in a 80/20 ratio, with the principal isomer PPh 2 Cy cis to the N atom. This was confirmed by 1 H, 13 C, and 31 P NMR spectra of the complex. The effective cone angle, θ E [11], of 156.48(2)°is similar to related compounds angles which are in the range of 154-157° [12][13][14][15].…”

“…The title complex forms part of a study which investigates complexes containing 2 ]-type complex will be substituted by triphenyl phosphine, with the product being one of two possible isomers [5], has been confirmed [6][7][8]. In each case the CO-group trans to the N-atom will be substituted, attributed to the larger trans-influence of the N-donor atom over the O-atom.…”
