Abstract: The title compound, CH₇N₄⁺·C₄H₃O₄^-, is a molecular salt in which the aminoguanidinium cations and fumarate monoanions are close to planar, with maximum deviations of 0.011 (1) and 0.177 (1) Å, respectively. The crystal packing is stabilized by intermolecular N-HO and O-HO hydrogen bonds.
