Abstract

In the title compound, C12H9N2+·Br−, the protonated tricyclic ring system is slightly twisted, with a dihedral angle of 3.9 (1)° between the two outer benzene rings. In the crystal, N—H⋯Br and C—H⋯Br hydrogen bonds link two cations and two bromide anions into centrosymmetric assemblies, which are further packed into stacks along [010] via π–π inter­actions between the aromatic rings [centroid–centroid distance = 3.725 (4) Å].
