2-(4,5-Dimeth-oxy-2-nitro-phen-yl)-4-meth-oxy-3-methyl-9-phenyl-sulfonyl-9H-carbazole

Abstract

In the title compound, C28H24N2O7S, the carbazole system is essentially planar, with a maximum deviation of 0.0644 (19) Å for the C atom connected to the 4,5-dimeth-oxy-2-nitro-phenyl group. The dihedral angle between the carbazole moiety and the dimethoxy-substituted nitrophenyl ring is 58.55 (7)°. The sulfonyl group forms two intra-molecular C-H⋯O bonds with the adjacent carbazole system, forming two cyclic S(6) motifs. In the crystal, mol-ecules are linked along the a axis in bands consisting of cyclic R 3 (3)(15) motifs through two further C-H⋯O hydrogen bonds.

The molecular structure of the title compound with the atom numbering scheme, displacement ellipsoids are drawn at 30% probability level. H atoms are present as small spheres of arbitary radius. The intramolecular C—H···O hydrogen bonds, which are generate S(6) ring motifs, shown as a dashed lines (see Table 1 for details).
