title: Triphen-yl[(4-phenyl-benzo-yl)meth-yl]phospho-nium trifluoro-methane-sulfonate.
abstract: In the cation of the title compound, C(32)H(26)OP(+)·CF(3)O(3)S(-), the dihedral angle between the benzene rings of the biphenyl group is 42.37 (8)°. In the crystal, the cations and anions inter-act through inter-molecular C-H⋯O hydrogen bonds, forming chains parallel to the b axis. These chains are further linked by C-H⋯π stacking inter-actions into layers parallel to the bc plane.
