3-Ethenyl-1-(4-methylphenylsulfonyl)-1H-indole

Abstract

Two independent but very similar molecules comprise the asymmetric unit of the title compound, C17H15NO2S. The molecules have L-shapes with the dihedral angles between the fused-ring system (r.m.s. deviations = 0.036 and 0.019 Å, respectively) and the benzene ring being almost the same, i.e. 82.98 (12) and 84.46 (13)°, respectively. The terminal ethenyl group is almost coplanar with the ring to which it is connected [C—C—C—C torsion angles = −173.7 (4) and −171.7 (4)°, respectively]. Supramolecular arrays parallel to (-124) stabilized by C—H...O and C—H...π interactions feature in the crystal packing.
