In the title compound, C(17)H(13)NO(2), two mol-ecules crystallize in the asymmetric unit. The dihedral angle between the mean planes of the quinoline and benzene rings are 78.3 (4) and 88.2 (3)°. The carboxyl-ate group is twisted slightly from the quinoline ring by 7.1 (2) and 13.3 (4)°, respectively. In the crystal, weak C-H⋯O inter-actions are observed. Further stabilization is provided by weak π-π stacking inter-actions, with centroid-centroid distances of 3.564 (9)/3.689 (2) and 3.830 (1)/3.896 (5)Å, respectively.
在标题化合物C(17)H(13)NO(2)中，两个分子在不对称单元中结晶。喹啉环和苯环平均平面之间的二面角分别为78.3 (4)°和88.2 (3)°。羧酸根分别相对于喹啉环扭转了7.1 (2)°和13.3 (4)°。在晶体中，观察到弱的C-H⋯O相互作用。通过弱的π-π堆积相互作用进一步提供了稳定性，其质心-质心距离分别为3.564 (9)/3.689 (2) Å和3.830 (1)/3.896 (5) Å。
