title: (Z)-1,1-Dicyano-2-(4-fluoro-phen-yl)-3-(1-hexyl-pyridin-1-ium-4-yl)prop-2-en-1-ide.
abstract: The title compound, C(22)H(22)FN(3), exists as a zwitterion with the negative charge on the dicyano-methanide group and the positive charge on the pyridinium N atom. The mol-ecule 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.
