Crystal structure of (E)-2-{[(6-methoxy-1,3-benzo-thiazol-2-yl) imino]methyl}phenol

Abstract

The title compound, C15H12N2O2S, crystallizes in the orthorhombic space group Pna21, with two molecules in the asymmetric unit (Z = 2). Each molecule consists of a 2-hydroxy Schiff base moiety linked through a spacer to a 2-aminobenzothiazole moiety. Each molecule contains an intramolecular hydrogen bond between the - OH group and imine N atom, forming a six-membered ring. The two independent molecules are linked by a pair of C - H⋯ O hydrogen bonds, forming dimers with an R22(20) ring motif. These dimers are further lined into sheets in the ab plane by weak intermolecular C - H⋯N interactions. The structure was refined as an inversion twin.
