Crystal structures of three carbazole derivatives: 12-ethyl-7-phenylsulfonyl-7H-benzofuro[2,3-b]carbazole, (1), 2-(4,5-dimethoxy-2-nitrophenyl)-4-hydroxy-9-phenylsulfonyl-9H-carbazole-3-carbaldehyde, (2), and 12-phenyl-7-phenylsulfonyl-7H-benzofuro[2,3-b]carbazole, (3)

Crystal structures of three carbazole derivatives: 12-ethyl-7-phenylsulfonyl-7H-benzofuro[2,3-b]carbazole, (1), 2-(4,5-dimethoxy-2-nitrophenyl)-4-hydroxy-9-phenylsulfonyl-9H-carbazole-3-carbaldehyde, (2), and 12-phenyl-7-phenylsulfonyl-7H-benzofuro[2,3-b]carbazole, (3)

The three title compounds, C26H19NO3S, (1), C27H20N2O8S, (2), and C30H19NO3S, (3), are carbazole derivatives, where (1) and (3) are heterocycle-containing carbazoles with a benzofuran moiety fused to a carbazole unit. In (2), a dimethoxynitrophenyl ring is attached to the carbazole moiety. In the th...
