The asymmetric unit of the title hybrid compound, (C9H8N)[FeCl4]Cl, comprises a tetrahedral tetrachloridoferrate(III) anion, [FeCl4]−, a Cl− anion and two quinolinium cations. There are N—HCl hydrogen-bonding interactions between the protonated N atoms of the quinolinium cations and the chloride anion, which together with π–π stacking between adjacent quinolinium rings [centroid-to-centroid distances between C6 and C5N rings in adjacent stacked quinolinium cations of 3.609 (2) and 3.802 (2) Å] serve to hold the structure together.

In the anion of the title hydrated molecular salt, C9H8N+·C8H4NO6−·H2O, the protonated carboxyl and nitro groups makes dihedral angles of 27.56 (5) and 6.86 (8)°, respectively, with the attached benzene ring, whereas the deprotonated carboxy group is almost orthogonal to it with a dihedral angle of 80.21 (1)°. In the crystal, the components are linked by O—HO and N—HO hydrogen bonds, generating [001] chains. The packing is consolidated by weak C—HN and C—HO interactions as well as aromatic π–π stacking [centroid-to-centroid distances: 3.7023 (8) & 3.6590 (9)Å] interactions, resulting in a three-dimensional network.

In the title salt, each cation shows a moderate distortion between the planes of the amide groups and the quinolinium rings. The trifluoromethanesulfonate anions are linked to organic cations via N—HO hydrogen-bonding interactions involving the NH amide groups. In the crystal, weak C—HO hydrogen bonds and π-stacking interactions between the quinolinium and phenyl rings link the organic cations into chains.

A new mixed-valence CuI/CuII three-dimensional coordination polymer incorporating 2-(pyrazin-2-yl)quinoline-4-carboxylic acid was synthesized and characterized. The ligand was also isolated as its hydrated hydrochloride salt. The compounds show luminescence and the ligand structure was rationalized by means of quantum-chemical calculations.

In the cation of the title salt, C12H14N3O+·C24H20B−, the dihedral angle between the quinoline ring and the mean plane of the urea fragment is 61.51 (5)°. In the crystal, the cations interact through weak C—HO hydrogen bonding, forming a zigzag chain along the c-axis direction; the cations and anions are involved in weak intermolecular C—Hπ and N—Hπ interactions as donors and acceptors, respectively.
