title: trans-Carbonyl-chloridobis[dicyclo-hex-yl(4-isopropyl-phen-yl)phosphane]rhodium(I) acetone monosolvate.
abstract: The title rhodium Vaska-type complex, trans-[RhCl{P(C(6)H(11))(2)(C(6)H(4)-4-C(3)H(7))(2)}(2)(CO)], crystallizes with an accompanying acetone solvent mol-ecule. The metal atom shows a distorted square-planar coordination environment with selected important geometrical parameters of Rh-P = 2.3237 (6) and 2.3253 (6) Å, Rh-Cl = 2.3724 (6) Å, Rh-C = 1.802 (2) Å, P-Rh-P = 173.42 (2)° and Cl-Rh-C = 179.13 (7)°. Effective cone angles for the two P atoms are 165 and 161°, respectively. Both isopropyl groups and the acetone mol-ecule are disordered with occupancy values of 0.523 (5):0.477 (5), 0.554 (8):0.446 (8) and 0.735 (4):0.265 (4), respectively. The crystal packing is stabilized by weak C-H⋯O and C-H⋯Cl contacts.
