A nearly orthogonal relationship is found for the ring systems in the title compound, C15H10N2O3, with the dihedral angle between the rings being 86.13 (11)°. The nitro group is approximately coplanar with the pyridine ring to which it is connected [the O—N—C—C torsion angle = −1.8 (4)°]. This coplanarity allows for the close approach of these residues in the enabling the formation of N—O⋯π(pyridine) interactions [3.547 (4) Å]. Further consolidation of the crystal packing is afforded by weak π–π interactions [centroid–centroid distances = 3.9576 (16) and 3.9822 (16) Å].

2-Naphthol (2.88 g, 20 mmol) and sodium hydroxide (0.80 g, 20 mmol) were dissolved in water (50 ml) and to the solution was added 2-chloro-5-nitropyridine (3.17 g, 20 mmol) dissolved in THF (50 ml). The mixture was heated for 7 h. Water was added and the organic phase extracted with chloroform. The chloroform solution was dried over sodium sulfate; slow evaporation led to the formation of colourless crystals.
Hydrogen atoms were placed at calculated positions (C—H 0.93 Å) and were treated as riding on their parent carbon atoms, with U(H) set to 1.2Ueq(C). The naphthalene fused-ring was refined as two fused hexagons with C≐C distances fixed at 1.39 Å.

In continuation of structural studies of nitro-pyridine derivatives (Nasir et al., 2010), the title compound was synthesized and characterized crystallographically. The molecule of (I), Fig. 1, is highly twisted as seen in the near orthogonal relationship between the two ring systems with the dihedral angle formed between the nitro-pyridine ring and naphthalyl ring being 86.13 (11)°. The nitro group is co-planar with the pyridyl ring to which it is attached with the O2—N2—C4—C3 torsion angle being -1.8 (4)°.
The most prominent feature of the crystal packing appears to be N—O···π interactions (Huang et al., 2008). The distance between O3···π(pyridyl) = 3.547 (4) Å, with the N2—O3···ring centroid(pyridyl)i angle = 81.9 (2)° for symmetry operation i: 1 - x, 1 - y, 1 - z. Similar interactions were reported in the crystal structure of 2-(4-methoxyphenoxy)-3-nitropyridine (Nasir et al., 2010). In (I), the N—O···π interactions along with weak π–π interactions, whereby both rings of the naphthalyl residue interact with the pyridyl ring, consolidate the crystal packing. The parameters associated with the π–π interactions are ring centroid(pyridyl)···ring centroid(C6–C11) and (C10–C15) = 3.9822 (16) and 3.9576 (16) Å, respectively, for ii: 1 - x, -1/2 + y, 3/2 - z. A view of the crystal packing is shown in Fig. 2.
