Triphen­yl[(4-phenyl­benzo­yl)meth­yl]phospho­nium trifluoro­methane­sulfonate

In the cation of the title compound, C32H26OP+·CF3O3S−, the dihedral angle between the benzene rings of the biphenyl group is 42.37 (8)°. In the crystal, the cations and anions interact through intermolecular C—H...O hydrogen bonds, forming chains parallel to the b axis. These chains are further linked by C—H...π stacking interactions into layers parallel to the bc plane.
