title: 4-(3-Eth-oxy-4-hydroxy-styr-yl)-1-methyl-pyridinium tosyl-ate monohydrate.
abstract: In the title compound, C(16)H(18)NO(2) (+)·C(7)H(7)O(3)S(-)·H(2)O, the dihedral angle between the pyridyl and benzene rings of the pyridinium cation is 0.2 (1)°. The benzene ring of the tosyl-ate anion makes a dihedral angle of 4.8 (2)° with the best mean plane of the pyridinium cation. The pyridinium cation and the tosyl-ate anion are hydrogen bonded to the water mol-ecule, and the crystal packing is further stabilized by inter-molecular C-H⋯O and π-π inter-actions [centroid-centroid separations of 3.648 (3) and 3.594 (2) Å.
