Phosphoric acid imidazolium dihydrogenphosphate

C. Chen, P. Y. Zavalij and M. S. Whittingham

Abstract: The title compound, H₃PO₄·C₃H₅N₂⁺·H₂PO₄^-, was synthesized during an investigation of the intercalation of imidazole into a series of VOPO₄ compounds. The asymmetric unit contains two phosphate species, which are disordered H₂PO₄^- and H₃PO₄, and one imidazolium cation, and has significant hydrogen bonding.
