11-[3-(Dimethylamino)propyl]-6,11-dihydrodibenzo[b,e]thiepin-11-ol

Abstract

There are two independent mol­ecules (A and B) in the asymmetric unit of the title compound, C19H23NOS. In each mol­ecule, the seven-membered thiepine ring is bent into a slightly twisted V-shape. The dihedral angles between the mean planes of the two benzene rings fused to the thiepine ring are 75.7 (5) in mol­ecule A and 73.8 (4)° in mol­ecule B. In both mol­ecules, an intra­molecular O—H⋯N hydrogen bond occurs. In the crystal, weak inter­molecular C—H⋯O and C—H⋯π-ring inter­actions are observed.
