ABSTRACT
The title compound, C12H7ClN2O2S, crystallizes with two molecules in the asymmetric unit. The molecular conformation is roughly planar for both these molecules with maximum deviations of 0.177 (3) and 0.076 (4) Å from their respective mean planes. In the crystal, strong N—H...N and weak but highly directional C—H...O hydrogen bonds provide the links between the molecules. The structure is further stabilised by aromatic π–π stacking interactions with centroid–centroid distances in the range 3.650 (3)–3.960 (3) Å.
