The title compound, C(4)H(12)N(2) (2+)·2C(2)H(2)NO(3) (-), contains a network of doubly protanated piperazinium cations (lying about centres of inversion) and dioxamate anions. The piperazinium dication adopts a typical chair conformation. The crystal structure is stabilized by cation-to-anion N-H⋯O and anion-to-anion N-H⋯O hydrogen bonds.
标题化合物C(4)H(12)N(2)(2+)·2C(2)H(2)NO(3)(-)包含由双质子化哌嗪鎓阳离子（位于对称中心）和二氧肟酸根阴离子构成的网络结构。哌嗪二价阳离子呈典型的椅式构象。晶体结构通过阳离子与阴离子之间的N-H⋯O氢键以及阴离子与阴离子之间的N-H⋯O氢键得以稳定。
