In the title complex, [Rh(acac)(CO)(PCy2Ph)] (acac = acetyl­acetonate, Cy = cyclo­hexyl) or [Rh(C5H7O2)(CO)(C18H27P)], the Rh atom is coordinated by one P [Rh—P = 2.2424 (9) Å], two O [Rh—O = 2.0783 (17) and 2.0411 (18) Å] and one C [Rh—C = 1.797 (3) Å] atoms in a slightly distorted square-planar geometry. The bite angle O—Rh—O is 88.20 (6)° and the calculated effective cone angle (θE) for the dicyclo­hexyl­phenyl phosphine is 163°.

Experimental. The intensity data was collected on a Bruker X8 Apex II 4 K Kappa CCD diffractometer using an exposure time of 50 s/frame. A total of 1140 frames were collected with a frame width of 0.5° covering up to θ = 26.75° with 98.0% completeness accomplized.

Spectroscopic data: 31P{H} NMR (CDCl3, 121.495 MHz, p.p.m.): 59.0 [d, 1 J(Rh—P) = 168.3 Hz]; IR υ(CO): 1948.8 cm-1; (CH2Cl2) υ(CO): 1967 cm-1.

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. planes.
