title: N-[3-(Benzene-sulfonamido)-prop-yl]benzene-sulfonamide.
abstract: In the title compound, C(15)H(18)N(2)O(4)S(2), 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, mol-ecules are linked by N-H⋯O hydrogen bonds, generating (001) sheets, and weak C-H⋯O inter-actions consolidate the packing.
