[2-(Benzyl­idene­amino)-4,5,6,7-tetra­hydro­benzo[b]thio­phen-3-yl](phen­yl)methanone

In the title compound, C(22)H(19)NOS, the cyclo­hexene ring of the tetra­hydro­benzo­thio­phenyl 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 thio­phene ring. The dihedral angles between the mean planes of the thio­phene 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 cyclo­hexene 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 inter­action links the mol­ecules into [001] chains.
