The triclinic unit cell of the title compound, N(2)H(6) (2+)·2C(6)H(3)N(2)O(4) (-)·2H(2)O, contains one doubly protonated hydrazine cation which lies on an inversion centre, two symmetry-related singly deprotonated 6-carboxy-pyridazine-3-carboxyl-ate anions and two symmetry-related solvent water mol-ecules. The anions inter-act via hydrogen bonds to form double ribbons which are bridged by hydrogen bonds donated by hydrazinediium cations and water molecules.

标题化合物N(2)H(6) (2+)·2C(6)H(3)N(2)O(4) (-)·2H(2)O的三斜晶胞包含一个位于对称中心的双质子化肼阳离子、两个对称相关的单去质子化6-羧基哒嗪-3-羧酸盐阴离子和两个对称相关的溶剂水分子。阴离子通过氢键相互作用形成双带，双质子化肼阳离子和水分子提供的氢键将这些双带连接起来。
