(E)-4-[4-(Diethyl­amino)­benzyl­idene­ammonio]­benzene­sulfonate

The title compound, C(17)H(20)N(2)O(3)S, 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 ring...

description The title compound, C(17)H(20)N(2)O(3)S, 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)°. 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 π–π inter­actions with a centroid–centroid distance of 3.8541 (6) Å. An O⋯O [2.8498 (11) Å] short contact is present.
