The title mol-ecule, C(25)H(22)F(6)N(2)O(3), adopts an open conformation whereby the quinoline and carboxyl-ate ester groups are orientated in opposite directions but to the same side of the piperidine ring so that the mol-ecule has an approximate U-shape. The piperidine ring adopts a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(14) loops.
标题分子C(25)H(22)F(6)N(2)O(3)呈开放构象,其中喹啉和羧酸酯基团朝相反方向,但位于哌啶环的同一侧,因此分子呈近似U形。哌啶环呈扭曲的船式构象。在晶体中,由O—H⋯O氢键对连接的反演二聚体形成R(2) (2)(14)环。
