3-(2H-Tetra-zol-5-yl)pyridinium trifluoro-acetate.

In the cation of the title compound, C(6)H(6)N(5) (+)·CF(3)COO(-), the pyridine and tetra-zole rings are nearly coplanar, making a dihedral angle of 2.49 (19)°. In the crystal, the cations and anions are connected by inter-molecular N-H⋯O and N-H⋯(F,O) hydrogen bonds, forming centrosymmetric [2 + 2] aggregates, which stack along the a axis.
