Abstract
The title compound, C12H10BrN3O3S, crystallizes with two crystallographically independent molecules in the asymmetric unit. The dihedral angles between the two six-membered rings in the molecules are 34.1 (3) and 45.1 (2)degrees. In the crystal structure, molecules are connected via N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonding.
