Abstract: The title compound, C22H22FN3, exists as a zwitterion with the negative charge on the dicyanomethanide group and the positive charge on the pyridinium N atom. The molecule adopts a Z conformation about the central C=C bond. The dihedral angle between the pyridinium and benzene rings is 65.65 (5)°. Weak C-H...N hydrogen bonding is present in the crystal structure.
