The title compound, C(6)H(8)N(3) (+)·Cl(-), crystallizes with two formula units in the asymmetric unit. The cations are non-planar with the -C(NH(2))(2) groups twisted relative to the ring planes by 36.7 (3) and 37.8 (3)°. The cations are linked into chains through N-H⋯N hydrogen bonds. N-H⋯Cl hydrogen bonds link the chains into a three-dimensional network.
