Crystal structure, Hirshfeld surface and photo-physical analysis of 2-nitro-3-phenyl-9H-carbazole.

ABSTRACT: The title compound, C₁₈H₁₂N₂O₂, was synthesized from a di-nitro-biphenyl-benzene derivative using a novel modification of the Cadogan reaction. The reaction has several possible ring-closed products and the title compound was separated as the major product. The X-ray crystallographic study revealed that the carbazole compound crystallizes in the monoclinic P space group and possesses a single closed Cadogan ring. There are two independent mol-ecules in the asymmetric unit. In the crystal, the mol-ecules are linked by N-H⋯O hydrogen bonding.
