1-{2-(E)-2-(2-Nitro­phen­yl)ethen­yl-1-phenyl­sulfonyl-1H-indol-3-yl}ethanone

摘要

In the title compound, C24H18N2O5S, the S atom has a distorted tetra­hedral configuration, with bond angles varying from 105.11 (7) to 119.98 (8)°. As a result of the electron-withdrawing character of the phenyl­sulfonyl group, the N—Csp ² bond lengths [1.414 (2) and 1.413 (2) Å] are slightly longer than the reported value of 1.355 (14) Å for N atoms with a planar configuration. The indole moiety is essentially planar, with a maximum deviation of 0.0177 (14) Å for the N atom. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 85.70 (7)° with the mean plane of the indole moiety. The mol­ecular structure features intra­molecular C—H⋯O hydrogen bonds, which generate S(6) and S(12) ring motifs. In the crystal, adjacent mol­ecules are linked via C—H⋯O hydrogen bonds, forming infinite C(7) chains running along the a-axis direction. The crystal packing also features C—H⋯π inter­actions, which form a three-dimensional structure.
