摘要：
In the title hydrated molecular salt, C18H23N2+center dot C6H4ClO3S-center dot H2O, which shows moderate biological activity against methicillin-resistant Staphylococcus aureus (MRSA), one ethyl group of the 2-[4-(diethylamino) styryl]-1-methylpyridinium cation is disordered over two orientations in a 0.604 (13):0.396 (13) ratio. The main part of the cation is nearly planar with a dihedral angle of 4.50 (10)degrees between the pyridinium and benzene rings. In the crystal, the components are linked by O-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot O weak interactions. Aromatic pi-pi stacking interactions with centroid-centroid separations of 3.7363 (12) and 3.7490 (13) angstrom also occur.
