چکیده
In the title compound, C27H21NO4S, the dihedral angles between the carbazole ring system (r.m.s. deviation = 0.015 Å) and the sulfur-bonded and directly linked benzene rings are 79.98 (11) and 53.51 (18)°, respectively. The benzene rings subtend a dihedral angle of 48.4 (2)°. The ethyl side chain of the ester group has an extended conformation [C-O-C-C = -172.3 (3)°]. In the crystal, inversion dimers linked by pairs of weak C-H⋯O hydrogen bonds generate R 2 (2)(22) loops. The dimers are linked by weak C-H⋯π and π-π [centroid-to-centroid distances ranging from 3.5042 (14) to 3.888 (2) Å] inter-actions, thereby forming a three-dimensional supra-molecular network.

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 benzo-furan moiety fused to a carbazole unit. In (2), a di-meth-oxy-nitro-phenyl ring is attached to the carbazole moiety. In the three derivatives, a phenyl-sulfonyl group is attached to the N atom of the carbazole unit. Co...

In the title compound, C25H15Cl2NO4S, the di-chloro-phenyl ring is twisted by 68.69 (11)° from the mean plane of the carbazole ring system [r.m.s. deviation = 0.084 (2)°]. The hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) graph-set motif.
