In the cation of the title compound, C6H6N5+·ClO4−, the pyridinium and tetrazole rings form a dihedral angle of 23.6 (1)°. In the weak intermolecular N—H⋯O and N—H⋯N hydrogen bonds link cations and anions into chains extending along the b axis.

Isonicotinonitrile (30 mmol), NaN 3 (45 mmol), NH4Cl (33 mmol) and DMF (50 ml) were added in a flask under nitrogen atmosphere and the mixture stirred at 110°C for 20 h. The resulting solution was then poured into ice-water (100 ml), and a white solid was obtained after adding HCl (6 M) till pH=6. The precipitate was filtered and washed with distilled water. Colourless block-shaped crystals suitable for X-ray analysis were obtained from the crude product by slow evaporation of an ethanol/HClO4 (50:1 v/v) solution.
All H atoms attached to C and N atoms were fixed geometrically and treated as riding with C–H = 0.93 Å (aromatic) and N–H = 0.86 Å with Uiso(H) =1.2Ueq(C or N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the past few years, more and more people have focused their attention on the chemistry of tetrazole derivatives because of their multiple coordination modes as ligands to metal ions and for the construction of novel metal-organic frameworks (Wang et al. 2005; Xiong et al. 2002; Wen, 2008). We report here the crystal structure of the title compound, 4-(2H-tetrazol-5-yl)pyridinium perchlorate).
In the title compound (Fig.1), the pyridine N atom is protonated. The pyridine ring makes a dihedral angle of 23.62 (1)° with the tetrazole ring. The geometric parameters of the tetrazole rings are comparable to those in related molecules (Wang et al. 2005; Dai & Fu, 2008).
The crystal packing is stabilized by N—H···O and N—H···N hydrogen bonds (Table 1) with the formation of zig-zag chains parallel to b axis.
