Ab Initio Structure Determination of Ammonium Hydrogen Alkyl Phosphates from X-ray Powder Diffraction Data

A. Neels, H. Stoeckli-Evans, J. Neels, A. Clearfield and D. Poojary

Synopsis: The structures of the ammonium hydrogen alkyl phosphates NH₄PO₂(OH)(OR) [R = Me (1), Et (2), Prⁱ (3)] are characterized by an extended hydrogen-bonding network involving the hydrogen phosphate units and the ammonium ions, forming double layers. These layers are separated from each other by van der Waals contacts between the hydrophobic alkyl groups.
