چکیده
In the title salt, C(6)H(7)N(6) (+)·Cl(-), there are two organic cations with similar conformations and two chloride anions in the asymmetric unit. The pyridine and tetra-zole rings are essentially coplanar in each cation, with dihedral angles of 4.94 (15) and 5.41 (14)°. The pyridine N atoms are protonated. The crystal packing is stabilized by N-H⋯N and N-H⋯Cl hydrogen bonds, forming an infinite sheets parallel to the (101).
