In the title compound, C(12)H(17)N(2)O(5)P, the phospho-nate group is almost orthogonal to both the ethyl groups, with a dihedral angle of 83.75 (11)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯O hydrogen bonds with an R(2) (2)(20) graph-set motif. The crystal structure is further consolidated by weak C-H⋯π inter-actions.
在标题化合物C₁₂H₁₇N₂O₅P中，膦酸酯基团与两个乙基几乎呈正交，二面角为83.75 (11)°。在晶体中，分子通过O—H⋯O氢键对连接成中心对称二聚体，具有R₂²(20) 图集模式。晶体结构通过弱C—H⋯π相互作用进一步巩固。
