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

Abstract

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].

Crystal structures of two new carbazole derivatives: 12-(4-nitrophenyl)-7-phenylsulfonyl-7H-benzofuro[2,3-b]carbazole and 2-methyl-4-(4-nitrophenyl)-9-phenylsulfonyl-9H-thieno[2,3-b]carbazole

“…A search of Cambridge Structural Database (CSD version 5.37; last update May 2016; Groom et al, 2016) yielded four hits for 7H-[1] benzofuran[2,3-b]carbazole and 47 hits for 9-(phenylsulfonyl)-9H-carbazole. However, the compound 7phenylsulfonyl-7H-benzofuran[2,3-b]carbazole (EYOFEE01; Panchatcharam et al, 2011), which crystallizes in P2 1 /c is the closest analogue of compound (I). The compound 2-methyl-9-(phenylsulfonyl)-9H-thieno[2,3-b]carbazole (IQOBIA; Sureshbabu et al, 2011), which crystallizes in space group P2 1 / c, is the closest analogue of compound (II).…”
