In the title compound, C16H11N3O3, the amide group is twisted away from the quinoline ring system and nitrobenzene ring by 8.02 (1)° and 54.92 (1)°, respectively. The crystal packing is stabilized by intermolecular C—H⋯O hydrogen bonds, and π–π interactions between the quinoline ring systems of inversion-related molecules, with a centroid–centroid distance of 3.4802 (13) Å.

O-Nitrobenzoic acid (2 mmol) and an excess of thionyl chloride (3 mmol) in dioxane (20 ml) were boiled under reflux for 6 h. The solution was distilled under reduced pressure and a yellow solid was obtained. 8-Aminoquinoline (2 mmol) in tetrahydrofuran (20 ml) was added to the yellow solid and boiled under reflux for 6 h. The solution was then cooled to ambient temperature and filtered to remove the tetrahydrofuran. The precipitate was dissolved in the dimethyl sulfoxide and allowed to stand for one month at ambient temperature, after which time white single crystals of the title compound suitable for X-ray diffraction were obtained.
All H atoms were placed in calculated positions, with C-H = 0.95 Å and N-H = 0.88 Å, and refined using a riding model, with Uiso(H) = 1.2Ueq(C,N).

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. |

Quinoline derivatives are a class of important compound for the treatment of bone metabolic disorders (Oku et al., 1998) and as H+-ATPases inhibitors (Oku et al., 1999). We report here the crystal structure of the title compound.
Bond lengths and angles in title molecule (Fig.1) are normal. The quinoline ring system is planar, with a maximum deviation of 0.033 (2) Å for atom C3. As a result of steric effects, the amide group is twisted away from the planes of the quinoline ring system and the nitrobenzene ring. The C5-C10 and C12-C17 planes form dihedral angles of 8.02 (1) and 54.92 (1)°, respectively, with the O1/N2/C8/C11 plane. The dihedral angle between the C12-C17 and O2/O3/N3/C13 planes is 36.83 (1)°.
The crystal packing is stabilized by C—H···O hydrogen bonds (Table 1), and π-π interactions between the benzene rings of the inversion-related molecules at (x, y, z) and (-x, 1 - y, 1 - z), with a centroid-centroid distance of 3.4802 (13) Å.
