title: 4-(4-Bromo-styr-yl)-1-methylpyridinium tosyl-ate.
abstract: In the cation of the title compound, C14H13BrN(+)·C7H7O3S(-), the dihedral angle between the benzene and pyridine rings is 8.34 (11)°. The Br atom is disordered over two positions with site occupancies of 0.74 (2) and 0.26 (2). The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-actions. The crystal structure exhibits weak C-H⋯O and π-π [centroid-centroid distance = 3.7466 (17) Å] inter-actions, forming a three dimensional network.
