Sumario:The title compound, C(14)H(10)BrN(3)O(3)S, crystallizes as two concomitant polymorphs that differ in colour (one yellow and one colourless). Only the structure of the colourless form could be determined. The mol­ecule exists in the thio­amide form with an intra­molecular N—H⋯O=C hydrogen bond across the thio­urea system. Mol­ecules are linked into layers parallel to (120) by Br⋯O(nitro) contacts [3.103 (1) Å], classical hydrogen bonds from the other NH function to the S atom and N(nitro)⋯O=C contacts. The layers are linked by weak C—H⋯O(nitro) hydrogen bonds to produce the observed three-dimensional network.
