Ethyl 1-benzenesulfonyl-2-[(E)-2-(2-methylphenyl)ethenyl]indole-3-carboxylate

In the title compound, C26H23NO4S, the phenyl, tolyl and ester groups make dihedral angles of 82.28 (5), 77.67 (6) and 8.52 (6)degrees, respectively, with the indole ring system. The S atom of the sulfonyl group is displaced by 0.1968 (4) angstrom from the indole mean plane. The molecular structure is stabilized by weak intramolecular C-H center dot center dot center dot O interactions. The crystal structure structure features short intramolecular C-H center dot center dot center dot O contacts and pi-pi stacking interactions between the phenyl and tolyl groups [centroid-centroid distance = 3.9448 (11) angstrom].
