Anhydrous guanidinium hydrogen fumarate: a two-dimensional hydrogen-bonded network structure

G. Smith, U. D. Wermuth, D. J. Young and P. C. Healy

Abstract: The title compound, CH₆N₃⁺·C₄H₃O₄^-, forms a two-dimensional hydrogen-bonded network structure. The guanidinium cations lie across crystallographic mirror planes while the hydrogen fumarate anions have inversion symmetry with the acid proton 50% disordered over the two carboxylate groups.
