Methyl 2-(2-hydroxybenzylideneamino)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate

In the title compound, C(17)H(17)NO(3)S, the cyclohexene ring is essentially planar, with a maximum deviation of 0.006 (1) Å. The cyclo-hexene ring adopts a half-chair conformation. The dihedral angle between the thio-phene and benzene rings is 29.7 (1)°. The mol-ecular structure exhibits intra-molecular O-H⋯O, O-H⋯N and C-H⋯S hydrogen bonds, which generate one S(5) and two S(6) motifs. There is also a C-H⋯π inter-action between the cyclo-hexene ring system and the π-system of the benzene ring.
