Description
Summary:The molecule of the title compound, C12H7BrN2O2S, 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 thiazole 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 molecules. In addition, C—H...π and π–π interactions [centroid–centroid distances = 3.950 (3)–4.024 (3) Å] provide additional stability to the interlayer regions in the lattice.
