organic compounds
In the structure of N-butyl-N-o-tolylbenzenesulfonamide, C17H21NO2S, the mean planes of the benzene rings are inclined to each other at 40.3 (1)°. The geometry around the S atom is considerably distorted from ideal tetrahedral geometry. Centrosymmetrically related pairs of molecules dimerize through C—HO hydrogen bonds. The crystal packing is stabilized by intermolecular C—HO hydrogen bonding.
organic compounds
In the title compound, C30H25NO3S, the phenylsulfonyl and methoxyphenyl groups are almost perpendicular to the indole unit, whereas the other phenyl ring is inclined at an angle of 68.9 (1)° to it. The benzene ring of the phenylsulfonyl substituent makes a dihedral angle of 68.0 (1)° with the benzene ring of the methoxyphenyl substituent. The molecular packing in the crystal is stabilized by weak intra- and intermolecular C—HO interactions.
organic compounds
In the title compound, C30H24ClNO3S, the phenylsulfonyl, chlorophenyl and methoxyphenyl rings are each almost perpendicular to the indole ring system. The crystal packing shows centrosymmetrically related pairs of molecules. Intermolecular C—HO interactions are present.
