Project description: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.

2-{[2,8-Bis(trifluoro-meth-yl)quinolin-4-yl](hy-droxy)meth-yl}piperidin-1-ium 3-amino-5-nitro-benzoate sesquihydrate.

Project description:The asymmetric unit of the title salt solvate, C(17)H(17)F(6)N(2)O(+)·C(7)H(5)N(2)O(4) (-)·1.5H(2)O, comprises a piperidin-1-ium cation, a 3-amino-5-nitro-benzoate anion, and three fractionally occupied [i.e. 0.414?(3), 0.627?(6) and 0.459?(5)] disordered water mol-ecules of solvation. The cation has an L shape with a C-C-C-C torsion angle of -102.9?(3)° for the atoms linking the quinolinyl group to the rest of the cation. In the anion, the carboxyl-ate and nitro groups are essentially coplanar with the benzene ring [O-C-C-C torsion angle = 179.7?(2)° and O-N-C-C torsion angle = -3.9?(3)°]. In the crystal, extensive O-H?O, O-H?F and N-H?·O hydrogen bonding leads to the formation of a layer in the ab plane.

1-{1-[2,8-Bis(trifluoro-meth-yl)-4-quin-olyl]-5-methyl-1H-1,2,3-triazol-4-yl}ethanone.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(10)F(6)N(4)O. The triazole ring is not coplanar with the quinoline ring system; the dihedral angle between the two planes being 74.47 (12) and 63.97 (13)° in the two mol-ecules. The crystal structure is characterized by inter-molecular C-H⋯F, C-H⋯N and C-H⋯O hydrogen bonding. Weak intra-molecular C-H⋯F inter-actions are observed. Disorder is observed in two F atoms of one of the trifluoro-methyl groups of one independent mol-ecule [occupancy ratios 0.77 (3):0.23 (3) and 0.77 (4):0.23 (4)] and in all three F atoms of one of the trifluoro-methyl groups of the second independent mol-ecule [occupancy ratios 0.520 (14):0.480 (14), 0.615 (17):0.385 (17) and 0.783 (11):0.217 (11)]. The O atom is also disordered over two positions with occupancies of 0.60 (13) and 0.40 (13) in the first mol-ecule.

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.

Project description: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 Oh-Cm-Cm-Na (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 [Cq-Cm-Cm-Na (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-molecular association in the crystal is the formation of chains along the a-axis direction, being stabilized by charge-assisted hydrogen-bonds. Thus, ammonium-N+-H?O-(carboxyl-ate) hydrogen bonds are formed whereby two ammonium cations bridge a pair of carboxyl-ate-O atoms, leading to eight-membered {?O?HNH}2 synthons. The resulting four-ion aggregates are linked into the supra-molecular chain via charge-assisted hydroxyl-O-H?O-(carboxyl-ate) hydrogen bonds. The connections between the chains, leading to a three-dimensional architecture, are of the type C-X??, for X = Cl and F. The analysis of the calculated Hirshfeld surface points to the importance of X?H contacts to the surface (X = F, 25.4% and X = Cl, 19.7%) along with a significant contribution from O?H hydrogen-bonds (10.2%). Conversely, H?H contacts, at 12.4%, make a relatively small contribution to the surface.

A kryptoracemic salt: 2-{[2,8-bis-(tri-fluoro-meth-yl)quinolin-4-yl](hy-droxy)meth-yl}piperidin-1-ium (+)-3,3,3-tri-fluoro-2-meth-oxy-2-phenyl-propanoate.

Project description:The asymmetric unit of the title salt, C17H17F6N2O(+)·C10H8F3O3 (-), comprises two piperidin-1-ium cations and two carboxyl-ate anions. The cations, each having an l-shaped conformation owing to the near orthogonal relationship between the quinolinyl and piperidin-1-ium residues, are pseudo-enanti-omeric. The anions have the same absolute configuration but differ in the relative orientations of the carboxyl-ate, meth-oxy and benzene groups. Arguably, the most prominent difference between the anions occurs about the Cq-Om bond as seen in the Cc-Cq-Om-Cm torsion angles of -176.1 (3) and -67.1 (4)°, respectively (q = quaternary, m = meth-oxy and c = carboxyl-ate). The presence of Oh-H⋯Oc and Np-H⋯Oc hydrogen bonds leads to the formation of a supra-molecular chain along the a axis (h = hy-droxy and p = piperidin-1-ium); weak intra-molecular Np-H⋯Oh hydrogen bonds are also noted. Chains are connected into a three-dimensional architecture by C-H⋯F inter-actions. Based on a literature survey, related mol-ecules/cations adopt a uniform conformation in the solid state based on the letter L.
