Abstract
The title compound, C24H20N2OS, crystallizes with two independent molecules (A and B) in the asymmetric unit, in each of which the cyclohexene rings adopt half-chair conformations. The mean plane of the indole ring is twisted from those of the phenyl and thiophene rings by 69.0 (7) and 8.3 (5)°, respectively, in molecule A and by 65.4 (9) and 6.7 (5)°, respectively, in molecule B. The dihedral angles between the mean planes of the phenyl and thiophene rings are 63.0 (4) and 58.8 (9)° in molecules 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 interactions are observed involving the thiophene and pyrrole rings of the two molecules, with a shortest intercentroid distance of 3.468 (2) Å.
