N-Acetyl-4-(benzene­sulfonamido)benzene­sulfonamide

In the mol­ecule 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 intra­molecular C—H⋯O inter­action results in the formation of a six-membered ring. In the crystal structure, inter­molecular N—H⋯O and C—H⋯O inter­actions link the mol­ecules into a three-dimensional network, forming R (2) (2)(20) ring motifs.
