摘要：
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)(degrees). In the crystal, the zwitterions are linked into a tape along the a axis by N-H...O hydrogen bonds. The crystal structure is further stabilized by weak C-H...O interactions and pi-pi interactions with a centroid-centroid distance of 3.8541 (6) A(degrees). An O...O [2.8498 (11) A(degrees)] short contact is present.
