In the crystal structure of the title compound, C4H5N2 +· C6HCl2O4 -, there are three crystallographically independent 1,2-diazinium cations and hydrogen chloranilate anions. The anions are held together by pairs of O - H⋯O hydrogen bonds to form two types of dimers, one of which is centrosymmetric. The 1,2-diazinium cations are linked on both sides of each dimer via bifurcated N - H⋯O hydrogen bonds to give two kinds of 2-2 cation-anion associations. The 2-2 associations are linked by inter-molecular C - H⋯O and C - H⋯N hydrogen bonds, forming a mol-ecular tape along the  direction. The tapes are further connected by C - H⋯O hydrogen bonds, forming a three-dimensional network.
