Crystal structure of (E)-2-{[(6-meth­oxy-1,3-benzo­thia­zol-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 R 2 2(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
