title: 3-(1H-Tetra-zol-5-yl)pyridinium chloride.
abstract: In the cation of the title compound, C(6)H(6)N(5) (+)·Cl(-), the pyridinium and tetra-zole rings are nearly coplanar, making a dihedral angle of 5.05 (12)°. The cations and anions are connected by inter-molecular N-H⋯Cl hydrogen bonds, forming a centrosymmetric [2 + 2] aggregate. The aggregates are stacked along the a axis.
