B. Shivachev, R. Petrova, K. Kossev and K. Troev

Abstract: The molecule of the title compound, C₅H₁₄NO₄P, exists as a zwitterion rather than as [1-(hydroxyethylamino)propyl]phosphonic acid, with the N atom of the amino group protonated and the phosphonic acid group negatively charged. In the crystal structure, the molecules are linked via extensive hydrogen bonding, forming layers parallel to (100).
