Abstract
In the title compound, C23H19Br2NO4S, the orientation of the phenylsulfonyl substituent with respect to the indole ring system is influenced by intramolecular C-H center dot center dot center dot O interactions. The sulfonyl-bound phenyl ring is orthogonal to the indole ring system. In the crystal structure, pi-pi stacking interactions involving the indole ring system link symmetry-related molecules into dimers.
