Abstract:
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).
