3,5-Diamino-1-phenyl-1,2,4-triazolium bromide.

The title salt, C(8)H(10)N(5) (+)·Br(-), crystallizes with two independent structural units in the asymmetric unit. The two independent cations have different conformations, the triazole and phenyl rings forming dihedral angles of 32.57†(6) and 52.27†(7)°. In both cations, the amino groups are planar (the sum of the angles at the N atom of each amino group is 360°) and conjugated with the triazole ring. Inter-molecular N-H⋯N and N-H⋯Br hydrogen bonds consolidate the crystal packing.
