9-[3-(Dimethylamino)propyl]-2-trifluoromethyl-9H-thioxanthen-9-ol

Abstract

In the title compound, C19H20F3NOS, the dihedral angle between the mean planes of the two benzene rings attached to the thioxanthene ring is 41.8 (7)°; the latter has a slightly distorted boat conformation. The F atoms are disordered over three sets of sites [occupancy ratio = 0.564 (10):0.287 (10):0.148 (5)] and the methyl groups are disordered over two sets of sites [occupancy ratio = 0.72 (4):0.28 (4)]. The crystal packing is stabilized by O—H...N and C—H...S hydrogen bonds and weak C—H...Cg interactions.
