2-(2-Hydroxyphenyl)-1,3-benzothiazole-6-carbaldehyde

Abstract

The molecule of the title compound, C14H9NO2S, is nearly planar, the maximum atomic deviation being 0.081 (2) Å. An intramolecular O—H...N bond generates an S(6) ring motif. In the crystal, inversion-related molecules linked by a pair of weak C—H...O hydrogen bonds form a supramolecular dimer. π–π stacking is observed between the thiazole and benzene rings of adjacent molecules, the centroid–centroid distance being 3.7679 (9) Å.
