title: Crystal structure of (E)-diethyl 2-[(1-phenyl-sulfonyl-1H-indol-3-yl)methyl-idene]succinate.
abstract: In the title compound, C23H23NO6S, the phenyl ring is perpendicular [dihedral angle = 89.34 (9)°] to the indole ring system. In the mol-ecule, the eth-oxy groups are each disordered over two sets of sites with occupancy ratios of 0.671 (6):0.329 (6) and 0.75 (3):0.25 (3). The mol-ecular conformation is consolidated by a weak C-H⋯O interaction, which generates an S(6) graph-set motif. The packing of the mol-ecules in the crystal structure features weak C-H⋯π inter-actions.
