| Summary: | In the title compound, C20H21N2+·C7H7O3S−·H2O, the cation is essentially planar, as indicated by the dihedral angle of 2.79 (13)° between the quinolinium and the dimethylaminophenyl rings, and exists in the E configuration. The π-conjugated planes of the cation and the anion are inclined to each other at a dihedral angle of 66.95 (12)°. The cation is linked to the anion through C—H...O hydrogen bonds and the anion is further linked with the water molecule by O—H...O hydrogen bonds, forming a three-molecule unit. These units are arranged in a face-to-face manner into a ribbon-like structure along the b axis. The ribbons are stacked along the c axis. The crystal structure is further stabilized by C—H...π interactions involving the dimethylaminophenyl and methylphenyl rings. A π–π interaction with a centroid–centroid distance of 3.6074 (19) Å is also observed. |
