1,2-Diazinium hydrogen chloranilate

In the crystal structure of the title compound, C(4)H(5)N(2) (+)·C(6)HCl(2)O(4) (-), 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 [230] direction. The tapes are further connected by C-H⋯O hydrogen bonds, forming a three-dimensional network.
