Abstract:
The mol-ecule of the title compound, C(14)H(9)NO(2)S, is nearly planar, the maximum atomic deviation being 0.081 (2) Å. An intra-molecular O-H⋯N bond generates an S(6) ring motif. In the crystal, inversion-related mol-ecules linked by a pair of weak C-H⋯O hydrogen bonds form a supra-molecular dimer. π-π stacking is observed between the thia-zole and benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7679 (9) Å.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
