The asymmetric unit of the title compound, C(4)H(12)N(2) (2+)·2C(5)H(3)N(2)O(4) (-)·4H(2)O, comprises one-half of a piperazine-1,4-diium cation, which lies on an inversion centre, a 2-carb-oxy-1H-pyrazole-4-carboxyl-ate anion and two water mol-ecules. An extensive network of inter-molecular O-H⋯O, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds between the cations, anions and water mol-ecules leads to a three-dimensional supra-molecular framework.
标题化合物C(4)H(12)N(2) (2+)·2C(5)H(3)N(2)O(4) (-)·4H(2)O的不对称单元包含位于对称中心的哌嗪-1,4-二鎓阳离子的一半、一个2-羧基-1H-吡唑-4-羧酸盐阴离子和两个水分子。阳离子、阴离子和水分子之间广泛的分子间O-H⋯O、N-H⋯O、N-H⋯N和C-H⋯O氢键形成了一个三维超分子框架。
