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.
在标题化合物C(4)H(5)N(2) (+)·C(6)HCl(2)O(4) (-)的晶体结构中，存在三个晶体学独立的1,2 - 二嗪鎓阳离子和氢氯冉酸盐阴离子。阴离子通过O - H⋯O氢键对结合在一起，形成两种类型的二聚体，其中一种是中心对称的。1,2 - 二嗪鎓阳离子通过分叉的N - H⋯O氢键在每个二聚体的两侧相连，形成两种2 - 2阳离子 - 阴离子缔合。2 - 2缔合通过分子间C - H⋯O和C - H⋯N氢键相连，沿[230]方向形成分子带。这些分子带通过C - H⋯O氢键进一步连接，形成三维网络。
