چکیده
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.

In the title salt, (C(17)H(17)F(6)N(2)O)(2)[Sn(C(6)H(5))(2)Cl(4)], the complete anion is generated by crystallograaphic inversion symmetry, giving a trans-SnC(2)Cl(4) octa-hedral coordination geometry for the metal atom. In the cation, the quinoline residue is almost normal to the other atoms, so that the ion has an L-shaped conformation [the C-C-C-C torsion angle linking the fused-ring systems...
