4-(1H-Tetra-zol-5-yl)pyridinium bromide.

In the cation of the title compound, C6H6N5+·Br−, the pyridine and tetra­zole rings are nearly coplanar, forming a dihedral angle of 6.41 (2)°. The organic cations inter­act with the Br− anions by N—H⋯Br hydrogen bonds, leading to the formation of chains parallel to the b axis.
