title: Diethyl [hydr-oxy(2-nitro-phen-yl)-meth-yl]phospho-nate.
abstract: In the title mol-ecule, C(11)H(16)NO(6)P, the nitro group is twisted out of the mean plane of the benzene ring at 29.91 (3)°. The two ethyl groups are disordered between two orientations in the ratios 0.784 (7)/0.216 (7) and 0.733 (6)/0.267 (6). Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
