The mol-ecule of the title compound, C(15)H(10)N(4)O(3)S(2), is almost planar (r.m.s. deviation = 0.1Å for all non-H atoms). An intra-molecular N-H⋯O=C hydrogen bond is observed. In the crystal, mol-ecules are connected into layers parallel to (10) by a classical inter-molecular hydrogen bond from the second NH group to a nitro O atom and by three weak… (More)
