Abstract

In the title mol­ecule, C18H12N2O4S, 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 intra­molecular C—H⋯O hydrogen bond links a nitro O atom to the carbazole skeleton. In the crystal, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules 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 inter­actions may also stabilize the structure.
