Abstract
In the title compound, C(15)H(16)N(2)O(5)S(2), the dihedral between the two aromatic rings is 81.33 (6)degrees. In the crystal, pairs of N-H center dot center dot center dot O hydrogen bonds link the molecules into centrosymmetric dimers, which are further connected via N-H center dot center dot center dot O hydrogen bonds into a chain running along [101].
