Abstract

The asymmetric unit of the title compound, C13H20NO+·PF6−, contains two cations, one complete anion and two half hexa­fluoro­phosphate anions having crystallographically imposed twofold rotation symmetry. In the cations, the morpholine rings are in a chair conformation. In the crystal, ions are linked by weak C—H⋯F hydrogen bonds into a three-dimensional network.
