The title mol-ecule, C(22)H(24)F(6)N(2)O(3), adopts a folded conformation whereby the carboxyl-ate residue lies over the quinolinyl residue, with the dihedral angle between the carbamate and quinoline planes being 41.64 (7)°. Helical supra-molecular C(7) chains sustained by O-H⋯O hydrogen bonds propagating along the a-axis direction feature in the crystal packing. The F atoms of one of the CF(3) groups are disordered over two orientations; the major component has a site occupancy of 0.824 (7).
标题分子C(22)H(24)F(6)N(2)O(3)呈折叠构象,其中羧酸根残基位于喹啉基残基上方,氨基甲酸酯平面与喹啉平面之间的二面角为41.64 (7)°。晶体堆积中存在由O—H⋯O氢键维持的沿a轴方向传播的螺旋超分子C(7)链。其中一个CF(3)基团的F原子在两个取向上无序;主要组分的占有率为0.824 (7)。
