2-Phenyl-1H-imidazol-3-ium hydrogen fumarate-fumaric acid (2/1)

H. Guo, X. Zhang and J.-X. Li

Abstract: The asymmetric unit of the title compound, C9H9N2+·C4H3O4-·0.5C4H4O4, consists of one 2-phenylimidazolium cation, one hydrogen fumarate anion and half a fumaric acid molecule, which lies on an inversion center. N-H...O and O-H...O hydrogen bonds connect the cations, anions and fumaric acid molecules into sheets parallel to the (102) plane.
