The title compound, (C(6)H(9)N(2))(2)[CuCl(4)], contains a distorted tetra-hedral [CuCl(4)](2-) anion and two protonated amino-pyridinium cations. The geometries of the protonated amino-pyridinium cations reveal amine-imine tautomerism. The crystal packing is influenced by N-H⋯Cl and C-H⋯Cl hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.635 (4) and 3.642 (4)°].
