چکیده
In the title compound, C(14)H(13)N(2) (+)·Br(-), the 1-(4-cyano-benz-yl)-4-methyl-pyridinium cation has a Λ-shaped conformation, and the dihedral angle between the benzene and pyridinium rings is 75.8 (2)°. In the crystal, two cations form a dimer through π-π inter-actions between pyridine rings [the centroid-centroid distance is 3.685 (1) Å].

In the crystal of the title mol-ecular salt, C(7)H(7)N(2) (+)·Br(-), the cations form inversion dimers via weak pairwise C-H⋯N hydrogen bonds; their mean planes are separated by 0.292 (6) Å. Weak C-H⋯Br inter-actions involving all of the remaining H atoms tie the cations and anions together into sets of inter-penetrating sheets. The title compound is isostructural with its iodide analogue.
