In the title compound, C7H4ClNO4·C9H7N, the two components are connected by an O—H⋯N hydrogen bond. In the hydrogen-bonded unit, the dihedral angle between the quinoline ring system and the benzene ring of benzoic acid is 3.15 (7)°. In the crystal, units are linked by intermolecular C—H⋯O hydrogen bonds, forming a tape along the c axis. The tapes are stacked along the b axis through a C—H⋯O hydrogen bond into a layer parallel to the bc plane.

Single crystals were obtained by slow evaporation from an acetonitrile solution (30 ml) of 2-chloro-4-nitrobenzoic acid (233 mg) and quinoline (150 mg) at room temperature.
C-bound H atoms were positioned geometrically (C—H = 0.95 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C). The O-bound H atom was found in a difference Fourier map and refined freely. The refined O—H distance is 0.95 (3) Å. Flack and Hooft parameters are 0.01 (5) and 0.02 (3), respectively.

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 was prepared in order to extend our study on D—H···A hydrogen bonding (D = N, O, or C; A = N, O or Cl) in quinoline–substituted benzoic acid systems (Gotoh & Ishida, 2009; Gotoh et al., 2010).
In the crystal structure of the title compound, no acid-base interaction involving proton transfer is observed between the two components, which are linked by an O—H···N hydrogen bond (Table 1 and Fig. 1). In the hydrogen-bonded unit, the dihedral angle between the quinoline ring system and the benzene ring of the benzoic acid is 3.15 (7)°. The carboxyl plane makes dihedral angles of 43.0 (2) and 39.9 (2)°, respectively, with the quinoline ring system and the benzene ring. The two components are further linked by intermolecular C—H···O hydrogen bonds (Table 1), forming a tape along the c axis and the tapes are stacked along the b axis through an C—H···O hydrogen bond into a layer parallel to the bc plane (Fig. 2). No significant interaction is observed between the layers.
