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

Abstract

In the title compound, C17H17NO3S, the cyclohexene ring is essentially planar, with a maximum deviation of 0.006 (1) angstrom. The cyclohexene ring adopts a half-chair conformation. The dihedral angle between the thiophene and benzene rings is 29.7 (1)degrees. The molecular structure exhibits intramolecular O-H center dot center dot center dot O, O-H center dot center dot center dot N and C-H center dot center dot center dot S hydrogen bonds, which generate one S(5) and two S(6) motifs. There is also a C-H center dot center dot center dot pi interaction between the cyclohexene ring system and the pi-system of the benzene ring.
