title: Crystal structure of 3-benzoyl-2-[(5-bromo-2-hydroxy-3-meth-oxy-benzyl-idene)amino]-4,5,6,7-tetra-hydro-benzo[b]thio-phene.
abstract: In the cyclo-hexene ring of the title compound, C23H20BrNO3S, the -(CH2)4- atoms are positionally disordered [occupancy ratio = 0.753 (6):0.247 (6)]. The ring has a half-chair conformation for both the major and minor components. The dihedral angles between the mean plane of the thio-phene ring and those of the benzene and phenyl rings are 35.2 (4) and 57.7 (3)°, respectively. The planes of the two aryl rings are twisted with respect to each other by 86.4 (6)°. In the mol-ecule, there is an O-H⋯N hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming chains parallel to [100].
