title: trans-Carbonyl-chloridobis[diphen-yl(4-vinyl-phen-yl)phosphane-κP]rhodium(I).
abstract: In the title compound, trans-[RhCl(C(20)H(17)P)(2)(CO)], the Rh(I) atom is situated on a center of symmetry, resulting in a statistical 1:1 disorder of the chloride [Rh-Cl = 2.383 (2) Å] and carbonyl [Rh-C = 1.752 (7) Å] ligands. The distorted trans square-planar environment is completed by two P atoms [Rh-P = 2.3251 (4) Å] from two diphen-yl(4-vinyl-phen-yl)phosphane ligands. The vinyl group is disordered over two sets of sites in a 0.668 (10):0.332 (10) ratio. The crystal packing exhibits weak C-H⋯Cl and C-H⋯O hydrogen bonds and π-π inter-actions between the phenyl rings of neighbouring mol-ecules, with a centroid-centroid distance of 3.682 (2) Å.
