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.Entities:

| 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. |
