Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811051853
Abstract: The title complex, {(C16H12FN2)[PbI3]}n, consists of 1-[(2-fluorobenzylidene)amino]quinolinium cations and a polymeric PbI3 anion formed by face-sharing PbI6 octahedra. These octahedra form straight and regular infinite chains along the b axis. In the asymmetric unit, one cation and one anionic [PbI3] fragment are observed in general positions. Polymeric chains are produced by the glide plane perpendicular to the a axis.

Abstract: The organic–inorganic hybrid, {(C6H13N3)2[Pb3I10]}n, was obtained by the reaction of 1-(3-ammoniopropyl)imidazolium triiodide and PbI2 at room temperature. The structure contains one-dimensional {[Pb3I10]4 }n polymeric anions spreading parallel to [001], resulting from face–face–edge association of PbI6 distorted octahedra. One of the PbII cations is imposed at an inversion centre, whereas the second occupies a general position. N—H...I hydrogen bonds connect the organic cations and inorganic anions.

Abstract: In the title compound, [Cd2I4(C6H14N2)2]n, there are two independent CdII ions. One CdII ion is coordinated in a slightly distorted octahedral coordination environment by four N atoms from two cyclohexane-1,2-diamine ligands and two iodido ligands. The other CdII ion is coordinated by four iodido ligands in a slightly distorted tetrahedral coordination environment. Two of the iodido ligands act as bridging ligands connecting CdII ions and forming a one-dimensional polymer along [010]. In the crystal, N—H...I hydrogen bonds connect the one-dimensional structure into a two-dimensional framework parallel to (001).

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811055462
Abstract: In the title compound, (C14H12NO)2[ZnCl4], the benzo[h]quinolinium groups are approximately planar, with maximum deviations of 0.049 (8) and 0.056 (9) . The methoxy groups are stabilized by intramolecular N—H...O hydrogen bonds. The structure also exhibits weak intermolecular N—H...Cl hydrogen bonds between the cations and anions. π–π interactions are present between the pyridinium and benzene rings [centroid–centroid distances = 3.640 (4), 3.728 (5) and 3.628 (5) ].
Kinetics and mechanism of the oxidation of methionine by quinolinium chlorochromate
Journal of the Serbian Chemical Society , 2005,
Abstract: The oxidation of methionine by quinolinium chlorochromate (QCC) has been studied, in the presence of chloroacetic acid, and in water acetic acid mixtures of varying mole fractions. The reaction is first order with respect to methionine, QCC and acid. The reaction rates were determined at three different temperatures (25, 35 and 45 °C) and the activation parameters were computed. The reaction rate increased with increasing mole fraction of acetic acid in the mixture and specific solvent solvent solute interactions were found to predominate (81 %). A solvation model and a suitable mechanism for the reaction are postulated.

Abstract: Quaternary quinolinium salts differing in alkyl chain length are members of a widespread group of cationic surfactants. These compounds have numerous applications in various branches of industry and research. In this work, the preparation of quinoline-derived cationic surface active agents differing in the length of the side alkyl chains (from C8 to C20) is described. An HPLC method was successfully developed for distinction of all members of the series of prepared long-chain quinolinium derivatives. In conclusion, some possibilities of intended tests or usage have been summarized. In vitro testing using a microdilution broth method showed good activity of a substance with a C12 chain length against Gram-positive cocci and Candida species.
4-[(2-Chloroethyl)amino]quinolinium chloride monohydrate

Abstract: In the title salt hydrate, C11H12ClN2+·Cl ·H2O, the quinolinium core is essentially planar (r.m.s. deviation = 0.027 ) with the chloroethyl side chain being almost orthogonal to the core [C—N—C—C torsion angle = 80.0 (3)°]. In the crystal packing, the water molecule bridges three species, forming donor interactions to two chloride anions and accepting a hydrogen bond from the quinolinium H atom. The chloride anion accepts a hydrogen bond from the amine N atom with the result that a two-dimensional supramolecular array is formed in the ac plane. A C—H...Cl interaction also occurs.

Abstract: The reaction of CdCl2, 18-crown-6 and KI in water yields the title coordination polymer, [{K(C12H24O6)}2Cd2I6]n. The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77 (2) and 0.23 (2). Two K(18-crown-6)+ units are linked by inversion symmetry, forming a [bis(μ2-18-crown-6)dipottasium] system with approximately square-planar K2O2 units. Inversion symmetry also generates the Cd2I6 fragment and the polymeric system is extended along the c axis by the formation of K—I—Cd bridges.
