Abstract

In the title compound, 2C14H14N+·C6H4ClO3S−·I−, each cation exists in an E configuration with respect to the ethenyl bond. The dihedral angle between the pyridinium and benzene rings is 3.98 (6)° in one of the cations and 9.88 (7)° in the other. The two cations are arranged in an anti­parallel manner with π–π inter­actions between pyridinium and benzene rings [centroid–centroid distance = 3.5805 (8) Å]. The benzene ring of the anion makes dihedral angles of 61.20 (6) and 64.25 (6)° with the pyridinium rings of the two cations. In the crystal, the cations are stacked in an anti­parallel manner along the a axis, while the anions are linked into chains along the same direction. The ions are linked into a three-dimensional network by C—H⋯I and C—H⋯O hydrogen bonds and C—H⋯π inter­actions. The crystal under investigation was an inversion twin, with a ratio of 61.7 (5):38.3 (5) for the two components.
