Abstract

The crystal structure of the title compound, C₁₉H₁₇NO₃S, was determined by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic crystal system with space group P2₁/c. The indole ring is essentially planar, with cyclo-propyl, aldehyde and p-toluene-sulfonyl groups attached at the C5, C2 and N1 positions, respectively. The aldehyde substituent is nearly coplanar with the indole ring, while the cyclo-propyl and p-tolyl rings are almost perpendicular to it. The crystal packing is mainly influenced by slipped π-π stacking inter-actions, along with weak C-H⋯O inter-actions involving the sulfonyl oxygen atoms. Hirshfeld surface analysis shows that H⋯H (46.6%), O⋯H/H⋯O (23.5%), C⋯H/H⋯C (16.0%) and C⋯C (8.0%) contacts make the major contributions to the crystal packing.
