چکیده
In the cation of the title compound, C(18)H(19)N(2)O(+)·PF(6) (-), the morpholine ring adopts the usual chair conformation and the dihedral angle between the benzene rings is 67.55 (11)°. The F atoms of the anion are disordered over two orientations with a refined occupancy ratio of 0.65 (2):0.35 (2). In the crystal, inter-molecular N-H⋯N hydrogen bonds link the cations into chains parallel to the c axis. The crystal packing is further enforced by inter-ionic C-H⋯F hydrogen bonds.
