چکیده
In the title compound, C(7)H(7)BrN(2)O, both the urea moiety [maximum deviation 0.003 (2) Å] and the benzene ring are essentially planar [maximum deviation 0.003 (2) Å] but are rotated with respect to each other by a dihedral angle of 47.8 (1)°. The crystal assembly is stabilized by N-H⋯O hydrogen bonds between all NH protons as conventional hydrogen bond donors and the C=O oxygen as a trifurcated hydrogen-bond acceptor. Both the overall mol-ecular geometry and the crystal packing of the title compound are very similar to those of N-phenyl-urea, which is underscored by a practically isostructural relationship between these two urea derivatives.

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...
