4-[(2′-Cyanobiphenyl-4-yl)methyl]morpholin-4-ium hexafluoridophosphate
Abstract
In the cation of the title compound, C18H19N2O+·PF6−, 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, intermolecular N—H...N hydrogen bonds link the cations into chains parallel to the c axis. The crystal packing is further enforced by interionic C—H...F hydrogen bonds.
