2-{[2,8-Bis(tri-fluoro-meth-yl)quinolin-4-yl](hy-droxy)meth-yl}piperidin-1-ium tri-chloro-acetate: crystal structure and Hirshfeld surface analysis.

ABSTRACT: The asymmetric unit of the centrosymmetric title salt, C₁₇H₁₇F₆N₂O⁺·C₂Cl₃O₂ ^-, comprises a single ion-pair. The hy-droxy-O and ammonium-N atoms lie to the same side of the cation, a disposition maintained by a charge-assisted ammonium-N-H⋯O(hy-droxy) hydrogen bond [the O_h-C_m-C_m-N_a (h = hy-droxy, m = methine, a = ammonium) torsion angle is 58.90 (19)°]. The piperidin-1-ium group is approximately perpendicular to the quinolinyl residue [C_q-C_m-C_m-N_a (q = quinolin-yl) is -178.90 (15)°] so that the cation, to a first approximation, has the shape of the letter L. The most prominent feature of the supra-mo
