The structure of the title compound, C 15 H 9 ClO 2 S, has a thioisocoumarin unit and a substituted phenyl group that are twisted at a dihedral angle of 33.40 ( 6) with respect to one another. In addition to weak O-HÁ Á ÁS interactions, C-HÁ Á ÁS/O/Cl-type interactions that stabilize the structure a
