چکیده
In the title compound, C(20)H(27)N(3)O(4), both cyclo-hexane rings adopt chair conformations. The benzene ring and the amide group are oriented at a dihedral angle of 62.1 (2)°. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains propagating in [010], which contain R(2) (2)(12) ring motifs.

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...
