4-(Benzylideneamino)benzenesulfonamide

Abstract

The title compound, C13H12N2O2S, formed by Schiff base condensation of benzaldehyde with sulfanilamide, crystallizes as discrete molecular species linked by N—H...N and N—H...O hydrogen bonds between the sulfamide nitrogen H atoms and the azamethine N and one sulfamide O atom, respectively, forming a two-dimensional array in the bc plane. The azamethine group is rotated slightly out of the benzaldehyde benzene plane [C—C—C—N torsion angle = 8.1 (3)°], while the dihedral angle between the two benzene rings is 30.0 (1)°.
