1-(2-Methylbenzyl)-1H-indole-3-carbaldehyde
In the title compound, C(17)H(15)NO, the benzene ring and the indole system are almost perpendicular, making a dihedral angle of 87.82 (6)°. The crystal packing is stabilized by C-H⋯O and π-π stacking inter-actions with centroid-centroid distances of 3.592 (4) Å between the pyrrole and the benzene rings in the indole systems of neighboring mol-ecules.

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(23)H(21)NO(3)S. The indole ring system is approximately perpendicular to the sulfonyl phenyl ring in both mol-ecules [dihedral angles = 85.42 (8) and 88.30 (9)°]. C-H⋯O inter-actions between mol-ecules stabilize the crystal structure.

In the title compound, C(28)H(24)ClNO(3), the dihedral angles between the central benzene ring and the indole ring system and the chlorobenzene ring are 70.81 (5) and 78.62 (5)°, respectively. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-action. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers with an R(2) (2)(14) motif.
