Ethyl 4,6-Dimethoxy-9-phenylsulfonylcarbazole-3-carboxylate

The crystal structure of the title compound, C₂₃H₂₁NO₆S, has been determined. The planar carbazole ring subtends an angle of 82.7 (4)° with the phenylsulfonyl group. The lengthening or shortening of the C-N bond distances [C5-N = 1.437 (4), C6-N = 1.418 (4) Å] are due to the electronic withdrawing character of the phenylsulfonyl group. The S atom is in the usual distorted tetrahedral configuration.
