Abstract: In the title solvated salt, C8H12N9+·ClO4-·CH3OH, the dihedral angle between the tetrazine and pyrazole rings is 26.05 (7)°. The two N atoms bonded to the 1,2,4,5-tetrazine ring deviate from the plane defined by its four N atoms by 0.234 (2) and 0.186 (2) Å. There is an intramolecular N-HN hydrogen bond between the protonated guanidine fragment and one of the tetrazine N atoms. In the crystal, two cations and two perchlorate anions are connected via N-HO hydrogen bonds into centrosymmetric assemblies. These assemblies are further linked into a two-dimensional network parallel to (100) via bifurcated O-H(N,N) hydrogen bonds formed with the bridging methanol molecules.
