Bis[(E)-1-methyl-4-styrylpyridinium] 4-chloro-benzene-sulfonate iodide.

ABSTRACT: In the title compound, 2C(14)H(14)N(+)·C(6)H(4)ClO(3)S(-)·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 anti-parallel manner with ?-? inter-actions 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 anti-parallel 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?? inter-actions. The crystal under investigation was an inversion twin, with a ratio of 61.7?(5):38.3?(5) for the two components.
