Crystal structure of ethyl 2-phenyl-9-phenyl-sulfonyl-9H-carbazole-3-carboxyl-ate.

ABSTRACT: 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?? and ?-? [centroid-to-centroid distances ranging from 3.5042?(14) to 3.888?(2)?Å] inter-actions, thereby forming a three-dimensional supra-molecular network.
