چکیده
Two mol-ecules of the title compound, C(15)H(13)N(3)O(3)S, are linked by an inter-molecular N-H⋯S hydrogen bond. There is also an intra-molecular N-H⋯O hydrogen bond, forming a six-membered ring. The steric restriction of the m-methyl and p-nitro groups, as well as the intra-molecular hydrogen bond, are the main factors influencing the mol-ecular conformation.

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 mol-ecule exists in the thio-amide form with an intra-molecular N-H⋯O=C hydrogen bond across the thio-urea system. Mol-ecules are linked into layers parallel to (120) by Br⋯O(nitro) contact...
