Bottom Line: In the title hydrated mol-ecular salt, C(16)H(19)N(2) (+)·C(6)H(4)ClO(3)S(-)·H(2)O, the 2-[4-(dimethyl-amino)-styr-yl]-1-methyl-pyridinium cation exists in an E configuration with respect to the C=C bond and is slightly twisted, with the dihedral angle between the pyridinium and benzene rings being 9.33 (10)°.In the crystal structure, the packing is stabilized by O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, which link the cations, anions and water mol-ecules into chains propagating in [010].These chains are stacked along the a axis by π-π inter-actions, with centroid-to-centroid distances of 3.6429 (12) and 3.6879 (12) Å; weak C-H⋯π inter-actions are also observed.

ABSTRACT
In the title hydrated mol-ecular salt, C(16)H(19)N(2) (+)·C(6)H(4)ClO(3)S(-)·H(2)O, the 2-[4-(dimethyl-amino)-styr-yl]-1-methyl-pyridinium cation exists in an E configuration with respect to the C=C bond and is slightly twisted, with the dihedral angle between the pyridinium and benzene rings being 9.33 (10)°. In the crystal structure, the packing is stabilized by O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, which link the cations, anions and water mol-ecules into chains propagating in [010]. These chains are stacked along the a axis by π-π inter-actions, with centroid-to-centroid distances of 3.6429 (12) and 3.6879 (12) Å; weak C-H⋯π inter-actions are also observed.
