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. pi-pi contacts between inversion-related benzene rings [centroid-centroid distance = 3.7828 (8) A] and two weak C-H...pi interactions may also stabilize the structure.eninfo:eu-repo/semantics/openAccessDerivativesArticle10.1107/S16005368110178182-s2.0-79957992463U82621754808N/AO142867WOS:000291216100070Q4
