Abstract: The title compound, C₂H₆N₅⁺·C₆H₂N₃O₇^-, was prepared by the equimolar reaction of 5-amino-1-methyltetrazole with picric acid. In the salt, the N⁴ atom of the tetrazole ring is protonated. Cations and anions in (I) are linked together by a complex set of hydrogen bonds, forming polymeric chains extending along the a axis, with van der Waals interactions between the chains.
