3-Methyl-1-tosyl-1H-indole-2-carbaldehyde.

ABSTRACT: The title indole derivative, C(17)H(15)NO(3)S, crystallizes with two independent mol-ecules in the asymmetric unit. The benzene ring of the tosyl group is almost perpedicular to the indole ring in both mol-ecules, with inter-planar angles of 82.60?(5)° and 81.82?(6)°. The two mol-ecules are, as a consequence, able to form an almost centrosymmetric non-bonded dimer, in which the molecules are linked by pairs of C-H?? inter-actions. The crystal structure displays a three-dimensional network of C-H?O inter-actions. A ?-? inter-action occurs between inversion-related indole rings with a centroid-centroid distance of 3.6774?(16)?Å and an inter-planar angle of 1.53?(15)°. This inter-action leads to a stacking of mol-ecules along the a axis.
