2-(4,5-Dimeth­oxy-2-nitro­phen­yl)-4-meth­oxy-9-phenyl­sulfonyl-9H-carbazole-3-carbaldehyde

In the title compound, C(28)H(22)N(2)O(8)S, the carbazole ring system is roughly planar, with a maximum deviation of 0.084 (3) Å for the C atom connected to the 4,5-dimeth­oxy-2-nitro­phenyl ring. The dihedral angle between the carbazole system and the dimeth­oxy-substituted nitro­phenyl ring is 57.05 (10)°. The aldehyde C atom deviates by 0.164 (5) Å from its attached carbazole ring system. The mol­ecular structure is stabilized by C—H⋯O inter­actions which generate two S(6) and one S(7) ring motif. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming R (3) (3)(15) ring motifs, which are further crosslinked by R (3) (2)(19) ring motifs, resulting in (002) layers. The crystal packing also features C—H⋯π inter­actions.
