The molecules of the title compound, [Rh(C9H6NO)(C18H21P)(CO)], pack with the H atoms of the phenyl and cyclohexyl rings at distances of 2.80–2.85 Å from the adjacent oxine ligand plane. The effective cone angle (ΘE) for the phosphine ligand is 151°. The bidentate oxine ligand has a bite angle of 79.41 (9)° and the Rh—P bond length is 2.2798 (8) Å.

Special details top
Experimental. The intensity data were collected on a Siemens SMART 1 K CCD
diffractometer using an exposure time of 20 s/frame. A total of 1350 frames
were collected with a frame width of 0.3° covering up to θ = 28.00° with
99.9% completeness accomplished. The first 50 frames were recollected at the
end of each data collection to check for decay; none was found. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
