N-[3-(Benzenesulfonamido)propyl]benzenesulfonamide

In the title compound, C15H18N2O4S2, the dihedral angle between the aromatic rings is 71.8 (2)°. The conformation of the central N—C—C—C—N fragment is gauche–gauche [torsion angles = 72.5 (5) and 65.7 (5)°]. Both N atoms adopt pyramidal geometries. In the crystal, molecules are linked by N—H...O hydrogen bonds, generating (001) sheets, and weak C—H...O interactions consolidate the packing
