{2-[(1H-Indol-3-yl-methyl-idene)amino]-4,5,6,7-tetra-hydro-benzo[b]thio-phen-3-yl}(phen-yl)methanone.

The title compound, C24H20N2OS, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit, in each of which the cyclo-hexene rings adopt half-chair conformations. The mean plane of the indole ring is twisted from those of the phenyl and thio-phene rings by 69.0 (7) and 8.3 (5)°, respectively, in mol-ecule A and by 65.4 (9) and 6.7 (5)°, respectively, in mol-ecule B. The dihedral angles between the mean planes of the phenyl and thio-phene rings are 63.0 (4) and 58.8 (9)° in mol-ecules A and B, respectively. In the crystal, N-H⋯O hydrogen bonds lead to the formation of an infinite chain along [101]. In addition, π-π stacking inter-actions are observed involving the thio-phene and pyrrole rings of the two mol-ecules, with a shortest inter-centroid distance of 3.468 (2) Å.
