title: (E)-1-[2-(4-Chloro-2-nitro-styr-yl)-1-phenyl-sulfonyl-1H-indol-3-yl]propan-1-one.
abstract: In the title compound, C25H19ClN2O5S, the phenyl ring forms dihedral angles of 79.62 (12) and 80.02 (13)° with the indole ring system and the benzene ring, respectively. The nitro group is twisted at an angle of 22.39 (11)° with respect to the attached benzene ring. In the crystal, mol-ecules assemble into double layers in the ab plane via C-H⋯O inter-actions.
