In the cation of the title compound, C18H19N2O+&#183;PF6&#8722;, the morpholine ring adopts the usual chair conformation and the dihedral angle between the benzene rings is 67.55&#8197;(11)&#176;. The F atoms of the anion are disordered over two orientations with a refined occupancy ratio of 0.65&#8197;(2):0.35&#8197;(2). In the crystal, intermolecular N&#8212;H...N hydrogen bonds link the cations into chains parallel to the c axis. The crystal packing is further enforced by interionic C&#8212;H...F hydrogen bonds
