7-Phenylsulfonyl-7H-benzofurano[2,3-b]carbazole

In the title compound, C24H15NO3S, the dihedral angle between the phenyl ring and the carbozole system is 74.91 (6)°. The S atom exhibits a distorted tetrahedral geometry [N—S—C = 104.85 (8)°; O—S—O = 119.59 (9)°]. The crystal structure is established by weak intermolecular π–π interactions [centroid–centroid distances = 3.583 (2)–3.782 (2) Å]
