In the title compound, C6H6N5+·NO3−, there are two different isomers of the cation within the The dihedral angles between the the pyridinium and tetrazole rings are 2.54 (15) and 13.36 (18)° in the two cations. In the crystal, the packing of ions is stabilized by N—H⋯O and N—H⋯(O,O) hydrogen bonds, forming clusters composed of four ion pairs.

Picolinonitrile (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 383 K 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 blocks of (I) were obtained from the crude product by slow evaporation of an ethanol/HNO3 (50:1 v/v) solution.
The tetrazole-ring H atoms were located in a difference map and freely refined. The other H atoms were fixed geometrically (C–H = 0.93 Å and N–H = 0.86 Å) and refined as riding 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. |

Tetrazole derivatives have found wide range of applications in coordination chemistry 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, 3-(1H-tetrazol-5-yl)pyridinium 3-(2H-tetrazol-5-yl)pyridinium nitrate (Fig. 1).
The title compound contains two different isomers of the cation, one with the H atom attached to the N2 and the other with the H atom attached to N9. Each isomer is built up by two different rings. The pyridinium and the tetrazole rings are nearly coplanar and only twisted from each other by a dihedral angle of 2.54 (15)° [13.36 (18)° for the second molecule]. The geometric parameters of the tetrazole rings are comparable to those in related molecules (Wang et al. 2005; Dai & Fu, 2008).
The packing of ions is stabilized by N—H···O hydrogen bonds, to form a zero-dimentional sheets parallel to the (1 0 0) plane that is composed of four pairs of ions (Table 1, Fig. 2).
