(E)-3-[4-(Benzo[d]oxazol-2-yl)styryl]-1-methylpyridin-1-ium hexafluoridophosphate

In the cation of the title mol­ecular salt, C21H17N2O+·PF6−, the pyridine ring and benzoxazole ring system are twisted with respect to the central benzene ring at dihedral angles of 23.75 (18) and 5.53 (16)°. In the crystal, the hexa­fluorido­phosphate anion accepts a weak C—H⋯F hydrogen bond from the cation to form an ion-pair.
