Abstract: The title compound, C₁₂H₁₉O₄P, has a distorted tetrahedral geometry around the P atom. The molecules form dimers with R₂²(10) ring motifs due to intermolecular O-HO hydrogen bonds. The double-bonded O atom of the phosphonate group behaves as an acceptor and the hydroxy group acts as a donor. Both of the ethyl groups are disordered with occupancies of 0.55:0.45 and 0.725:0.275.
