An orthorhombic polymorph of 2-(1,3-benzothiazol-2-yl)-6-ethoxyphenol

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.009 Å; R factor = 0.068; wR factor = 0.144; data-to-parameter ratio = 12.9.In the title molecule, C 15 H 13 NO 2 S, an intramolecular O-HÁ Á ÁN hydrogen bond forms an S(6) ring motif. The benzothiazole ring system and the benzene ring form a dihedral angle of 8.9 (3) Å . In the crystal, molecules are linked by weak C-HÁ Á ÁO hydrogen bonds, forming chains along the b axis. In addition, -interactions [centroid-centroid distances = 3.772 (4) and 3.879 (4) Å ] are observed. Related literature
