The title molecule, C12H9NO2, adopts a trans configuration about the olefinic double bond. The dihedral angle between the naphthalene ring system (r.m.s. deviation = 0.012 Å) and the nitroethenyl group (r.m.s. deviation = 0.032 Å) is 12.66 (5)°. The molecules are linked into a two-dimensional network parallel to the bc plane by C—H⋯O hydrogen bonds. The substituted benzene rings in adjacent networks are stacked with a centroid–centroid distance of 3.6337 (11) Å, indicating π–π interactions.

The title compound was synthesized according to the method reported in the literature (Cheng et al., 2007). Yellow single crystals suitable for X-ray diffraction were obtained by slow evaporation of a methanol solution.
All H atoms were placed in calculated positions, with C-H = 0.95 Å, and refined using a riding model, with Uiso(H) = 1.2Ueq(C).

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. |

β-Nitroolefins are a class of useful and versatile building blocks in organic synthesis (Barrett & Graboski, 1986). The author reports here, the crystal structure of the title compound.
Bond lengths and angles in the title molecule are normal. The molecule adopts a trans configuration about the olefinic double bond (Fig. 1). The naphthalene ring system is planar, with a maximum deviation of 0.021 (1) Å for atom C1. The dihedral angle between the C1-C9 and N1/O1/O2/C11/C12 planes is 12.66 (5)°. The molecules are linked into a two-dimensional network parallel to the bc plane by C—H···O hydrogen bonds (Table 1).
