| Summary: | In the molecule of the title compound, C14H10ClNO2S, the dihedral angle between the almost planar benzothiazole ring system [maximum deviation = 0.005 (2) Å] and the benzene ring is 1.23 (9)°. The conformation of the molecule is stabilized by an intramolecular O—H...N hydrogen bond, forming an S(6) ring motif. In the crystal, molecules are linked into layers parallel to the ac plane by C—H...O hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 3.7365 (12) Å].
