trans-Carbonylchloridobis(tri-p-tolylphosphine)rhodium(I) acetone solvate

The title compound, [RhCl(C21H21P)2(CO)]·C3H6O, was precipitated in trace yield from a reaction of RhCl(cod)(THP) with P(p-tol)3 in a 1:1 acetone-d6/CD3OD solution under a hydrogen atmosphere [p-tol = p-tolyl, THP = tris(hydroxymethyl)phosphine, P(CH2OH)3, and cod = 1,5-cyclooctadiene]. The complex displays a square-planar geometry around the RhI atom. The complex molecules and the acetone molecules are linked into a chain along the a axis by intermolecular C—H...Cl and C—H...O hydrogen bonds.
