In the title molecule, C10H11NO5, the methyl C atom deviates by 0.830 (6) Å from the mean plane of the remaining non-H atoms. In the crystal, weak C—H⋯O hydrogen bonds link the molecules into layers parallel to the bc plane.

4-Nitro-phenol (7 g) and 1-Bromo-butan-2-one (8.5 g) were dissolved in acetone, kalium carbonicum (7.5 g) was added to the mixture. Then the mixture was heated and refluxed by mechanical stirring at 70°C. Yellow solid was filtered off. This solid was dissolved in ethanol and single crystals suitable for X-ray structure analysis were obtained by the slow evaporation of the above solution after 3 days in air.
All H atoms were placed in calculated positions (N—H = 0.89 Å; C—H = 0.93 Å for Csp2 atoms and C—H = 0.96 Å and 0.97 Å for Csp3 atoms), assigned fixed Uiso values [Uiso = 1.2Ueq(Csp2) and 1.5Ueq(Csp3,N)] and allowed to ride.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, (I), has been obtain during the search for new organic compounds which demonstrate ferroelectric phase changes (Fu et al., 2009; Ye et al., 2006). Though the measured dielectric constant of (I) showed no dielectric disuniformity in the range 120–385 K (mp.393–402 K), herewith we present its crystal structure.
In (I) (Fig. 1), all bond lengths and angles are normal and correspond to those observed in tert-butyl 2-(4-nitrophenoxy)acetate (Ali et al., 2011). Atom C10 deviates at 0.830 (6) Å from the mean plane of the rest non-H atoms.Weak intermolecular C—H···O hydrogen bonds (Table 1) link the molecules into layers parallel to bc plane.
