(Received 14 November 2008; accepted 16 November 2008; online 20 November 2008)

In the title compound, C16H11N3O3, the amide group is twisted away from the plane of the quinoline benzene ring by 3.93 (5)°, but is twisted away from the nitro­benzene ring by 22.68 (4)°. A weak intra­molecular C—H⋯O hydrogen bond is observed. In the crystal structure, mol­ecules are linked into a chain along the a axis by inter­molecular C—H⋯O hydrogen bonds.

Comment top

Quinoline derivatives are a class of important compound as antagonists of TRPV1 (Westaway et al., 2006) and a sensitive and specific probe for studying MRP-drug interactions (Daoud et al., 2000). Previously, we have reported the crystal structures of (2-nitrophenyl)-N-(8-quinolyl)carboxamide (Lei et al., 2008a) and (3-nitrophenyl)-N-(8-quinolyl)carboxamide (Lei et al., 2008b). Now, we report here the crystal structure of the title compound (Fig.1).

Bond lengths and angles are normal. The quinoline ring system is planar, with a maximum deviation of 0.010 (7) Å for atom C5. As observed in related structures (Lei et al., 2008a,b), the amide group is twisted away from the planes of the quinoline benzene ring and 4-nitro substituted benzene ring. The C5—C10 and C12—C17 planes form dihedral angles of 3.93 (5)° and 22.68 (4)°, respectively, with the O1/N2/C8/C11 plane. The C12—C17 and O2/O3/N3/C15 planes are inclined at an angle of 2.58 (7)°. The dihedral angle between the N1/C2-C10 and C12-C17 planes is 26.36 (3)°. An intramolecular C7—H7···O1 hydrogen bond is observed.

The crystal packing is stabilized by C—H···O hydrogen bonds (Table 1). These hydrogen bonds link the molecules into a chain along the a axis.

Experimental top

p-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 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.

Refinement top

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).

Special details top

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.
