In the title compound, [RhCl{P(p-FC6H4)(3)}(3)]center dot CH3OH, the Rh atom adopts a distorted square-planar geometry. Rh, Cl and one P atom lie on a mirror plane, as does the solvent molecule. There are two intermolecular hydrogen bonds, one between the methanol O atom and an aryl H atom (2.51 angstrom), and one between the Cl atom and the hydroxy H atom of methanol [2.34 (3) angstrom]. The complex precipitates in trace amounts from a reaction between RhCl(cod)(thp) [cod is 1,5-cyclooctadiene and thp is tris(hydroxymethyl) phosphine] and P(p-FC6H4)(3) under argon in CD3OD. Two C6H4-F units are disordered over two positions; for one the site occupancy factors are ca. 0.53 and 0.47, for the other the values are ca. 0.64 and 0.36. The methyl H atoms of the solvent molecule are disordered across the mirror plane.
