4-Cyano-pyridinium bromide.
In the title compound, C(6)H(5)N(2) (+)·Br(-), the pyridine N atom is protonated and involved in an inter-molecular N-H⋯Br hydrogen bond which, together with weak C-H⋯N hydrogen bonds, results in the formation of a chain along the c axis. Weak inter-molecular C-H⋯Br inter-actions between pyridine H atoms and Br(-) anions connect these chains into a network parallel to the bc plane.
