Diethyl [hydroxy(2-nitrophenyl)methyl]phosphonate
Abstract
In the title molecule, C11H16NO6P, 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). Intermolecular O—H...O hydrogen bonds link the molecules into centrosymmetric dimers.
