9-(4-Nitro-phenyl-sulfon-yl)-9H-carbazole.

ABSTRACT: In the title mol-ecule, C(18)H(12)N(2)O(4)S, the carbazole skeleton is nearly planar [maximum deviation = 0.037?(1)?Å] and is oriented at a dihedral angle of 73.73?(5)° with respect to the benzene ring. An intra-molecular C-H?O hydrogen bond links a nitro O atom to the carbazole skeleton. In the crystal, inter-molecular C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between inversion-related benzene rings [centroid-centroid distance = 3.7828?(8)?Å] and two weak C-H?? inter-actions may also stabilize the structure.
