title: N-Acetyl-4-(benzene-sulfonamido)benzene-sulfonamide.
abstract: In the mol-ecule of the title compound, C(14)H(14)N(2)O(5)S(2), the dihedral angle between the aromatic rings is 77.75 (9)°. The acetamide group is planar [maximum deviation = 0.002 (3) Å] and oriented at dihedral angles of 13.49 (21) and 73.94 (10)° with respect to the aromatic rings. An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network, forming R(2) (2)(20) ring motifs.
