title: Bis(2-{[2,8-bis-(trifluoro-meth-yl)quinolin-4-yl](hydr-oxy)meth-yl}piperidin-1-ium) tetra-chloridodiphenyl-stannate(IV).
abstract: 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 is 100.9 (7)°]; the six-membered piperidin-1-ium ring has a chair conformation. An intra-molecular N-H⋯O inter-action occurs. In the crystal, N-H⋯Cl and O-H⋯Cl hydrogen bonds link the components into a supra-molecular chain propagating along the a axis. C-H⋯Cl inter-actions are also present.
