9-(4-Nitrophenylsulfonyl)-9H-carbazole
نویسندگان
چکیده
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. π-π contacts between inversion-related benzene rings [centroid-centroid distance = 3.7828 (8) Å] and two weak C-H⋯π inter-actions may also stabilize the structure.
