3-Benzyl-2-methyl-1-phenyl­sulfonyl-1H-indole

In the title compound, C₂₂H₁₉NO₂S, the two phenyl rings adopt a trans conformation with respect to the indole moiety. The indole system deviates slightly from planarity. The aromatic ring of the phenyl­sulfonyl group is almost perpendicular to the indole ring, while the benzyl ring is oriented at an angle of 77.01 (1)°. A zigzag C—H...O intermolecular hydrogen bond along the b axis and C—H...π interactions stabilize the crystal packing.

2-(1-Benzoyl-1-phenyl­ethyl)-3-phenyl­sulfanyl-1-phenyl­sulfonyl-1H-indole

In the title mol­ecule, C₃₅H₂₇NO₃S₂, the indole system is approximately planar. The phenyl rings of the phenyl­sulfonyl and phenyl­sulfanyl groups are oriented at angles of 74.69 (7) and 88.35 (9)°, respectively, to the indole ring system. The dihedral angle between the two phenyl rings of the di­phenyl­propanone moiety is 74.25 (10)°. Inversion-related mol­ecules form C—H...π interactions and C—H...O hydrogen bonds. The C—H...O intermolecular hydrogen bonds form a closed ring pattern in the crystal stucture.
