title: 1-{4-[(1H-1,2,4-Triazol-1-yl)meth-yl]benz-yl}-1H-1,2,4-triazol-4-ium perchlorate.
abstract: In the crystal structure of the title compound, C(12)H(13)N(6) (+)·ClO(4) (-), the cation, located about an inversion center, is monoprotonated, and one H atom is disordered over two sites on N atoms of the two triazole rings, each with an occupancy factor of 0.5. The perchlorate anion has C(2) symmetry, the Cl atom and one O atom lying on the twofold rotation axis; the anion is thus disordered over two sites of equal occupancy. In the cation, the triazole ring makes a dihedral angle of 84.75 (7)° with the plane of the benzene ring. In the crystal, inter-molecular N-H⋯N hydrogen bonding between the triazole and triazolium rings links the cations into a wave-like supra-molecular chain. Weak inter-molecular C-H⋯N and C-H⋯O hydrogen bonding is also present.
