Abstract:In the title compound, 2C14H14N+·C6H4BrO3S−·I−, two crystallographically independent cations exist in an E configuration with respect to the C=C ethenyl bond. One cation is approximately planar, whereas the other is twisted slightly, the dihedral angles between the pyridinium and phenyl rings of each cation being 0.96 (15) and 7.05 (16)°. In the crystal structure, the cations are stacked in an antiparallel manner along the a axis through weak C—H⋯π interactions and π–π interactions, with centroid–centroid d… Show more
