The asymmetric unit of the title compound, C19H15N, contains two crystallographically independent molecules. In both molecules, the planar carbazole moieties [maximum deviations = 0.037 (4) and 0.042 (3) Å] are oriented with respect to the adjacent benzene rings, at dihedral angles of 85.29 (8) and 89.89 (7)°, respectively. In the crystal structure, weak C-H...[pi] interactions are observed involving the carbazole rings.
