Abstract: In the title compound, C30H22N2O7S2, the configuration about the propene C=C bond is E. The indole unit is essentially planar, with a maximum deviation of 0.031 (3) Å. The dihedral angle between the planes of the phenyl rings of the two phenylsulfonyl groups is 80.95 (19)°. The central prop-2-ene-1-one group is oriented at a dihedral angle of 44.26 (11)° with respect to the nitrophenyl ring and at 39.24 (8)° with respect to the indole unit. The S atoms are in a distorted tetrahedral configuration. In the crystal, molecules are linked into centrosymmetric dimers via pairs of C-HO hydrogen bonds with an R22(24) graph-set motif. The crystal structure is stabilized by further C-HO interactions. Short intramolecular C-HO contacts result in several S(6) rings.
