چکیده
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.

Mol-ecules of the title compound, C(34)H(38)N(4)O(2), lie across crystallographic inversion centres. The crystal packing can be described by alternating zigzag chains along the c axis in which the molecules are linked by van der Waals interactions. There is an intra-molecular O-H⋯N hydrogen bond and the two benzene rings in the asymmetric unit make a dihedral angle of 79.81 (6)°.
