In the cation of the title salt, C9H13N2O2 (+)·C7H3N2O6 (-), the piperazine ring adopts a slightly distorted chair conformation. Twofold rotational disorder is exhibited by the furan ring in a 0.430 (4):0.570 (4) ratio. In the crystal, N-H⋯O hydrogen bonds link the ions into chains along [010]. Additional weak C-H⋯O inter-actions are observed, leading to a supra-molecular layer parallel to (011).
在标题盐C9H13N2O2(+)·C7H3N2O6(-)的阳离子中，哌嗪环呈轻微扭曲的椅式构象。呋喃环表现出双重旋转无序，比例为0.430 (4):0.570 (4)。在晶体中，N-H⋯O氢键将离子沿[010]连接成链。还观察到额外的弱C-H⋯O相互作用，导致形成平行于(011)的超分子层。
