Crystal Structure of 2-Nitro-5,6-dihydro-11H-benzo[a]carbazole

Abstract

The title compound, C₁₆H₁₂N₂O₂, consists of a nitro benzoato group fused to the a-face of the carbazole skeleton, in which the planar carbazole skeleton and benzene ring are also coplanar. It belongs to the space group P2₁/n with cell parameters a = 12.220(4), b = 6.9647(10), c = 15.304(3)Å and β = 97.414(3)°. Molecules are linked about inversion centres by N-H…O hydrogen bonds [N…O 2.965(5)Å] to form centrosymmetric dimers.
