Abstract

The title compound, C15H12N2O2S, crystallizes in the ortho-rhom-bic space group Pna21 , with two mol-ecules in the asymmetric unit (Z' = 2). Each mol-ecule consists of a 2-hy-droxy Schiff base moiety linked through a spacer to a 2-amino-benzo-thia-zole moiety. Each mol-ecule contains an intra-molecular 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 R (2) 2(20) ring motif. These dimers are further lined into sheets in the ab plane by weak inter-molecular C-H⋯N inter-actions. The structure was refined as an inversion twin.
