%X The title compound, C17H20N2O3S, synthesised from sulfanilic acid and 4-diethylaminobenzaldehyde, crystallized out as a zwitterion with the central N atom protonated. The zwitterion exists in an E conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 37.57 (5)¡ã. In the crystal, the zwitterions are linked into a tape along the a axis by N¡ªH...O hydrogen bonds. The crystal structure is further stabilized by weak C¡ªH...O interactions and ¦Ð¨C¦Ð interactions with a centroid¨Ccentroid distance of 3.8541 (6)  . An O...O [2.8498 (11)  ] short contact is present.
