Hydroxonium 1-ammonioethane-1,1-diyldiphosphonate

M. Li, W. Wen, W. Ha and L. Chang

Abstract: The title complex, H₃O⁺·NH₃C(CH₃)(PO₃H)₂^-, contains a hydroxonium ion and an NH₃C(CH₃)(PO₃H)₂^- anion. The three H atoms of H₃O⁺ form a pseudo-tetrahedron by being distributed over four positions with occupation factors of 0.75. Multiple N-HO and O-HO hydrogen bonds in the crystal structure form an intricate three-dimensional supramolecular network.
