[2-(Benzyl-idene-amino)-4,5,6,7-tetra-hydro-benzo[b]thio-phen-3-yl](phen-yl)methanone.

In the title compound, C22H19NOS, the cyclo-hexene ring of the tetra-hydro-benzo-thio-phenyl ring system adopts a slightly distorted half-chair conformation and is twisted slightly [7.5†(8)° for the major disorder component] from the mean plane of the thio-phene ring. The dihedral angles between the mean planes of the thio-phene ring and the phenyl rings are 65.7†(3) and 8.3†(4)°. The phenyl rings are twisted with respect to each other by 73.8†(7)°. Disorder was modeled for four C atoms of the cyclo-hexene ring over two sets of sites with an occupancy ratio of 0.659†(2):0.341†(2). In the crystal, a single weak C-H⋯O inter-action links the mol-ecules into [001] chains.
