Abstract
The mol-ecule of the title compound, C(12)H(7)BrN(2)O(2)S, is essentially planar with a maximum deviation of 0.234 (3) Å from the mean plane through all non-H atoms. The dihedral angle between the coumarin ring plane and that of the five-membered thia-zole ring is 12.9 (1)°. In the crystal, strong N-H⋯O, N-H⋯N and weak but highly directional C-H⋯O hydrogen bonds provide the links between the mol-ecules. In addition, C-H⋯π and π-π inter-actions [centroid-centroid distances = 3.950 (3)-4.024 (3) Å] provide additional stability to the inter-layer regions in the lattice.
