Source of materials

Hydrothermal reactions were carried out at 393 K for 3 d in a Teflon-lined acid digestion bomb with an internal volume of 25 mL followed by slow cooling at 6 K/h to room temperature. A single-phase product consisting of yellow crystals was obtained from a mixture of zinc perchlorate hexahydrate (1 mmol, 372.4 mg), 8-hydroxy-5-nitroquinoline (2 mmol, 380.3 mg), water (10 mL) and methanol (5 mL).

Experimental details

C-bound H atoms and N-bound H atoms were included in the riding model approximation with C—H = 0.93 Å and N—H = 0.86 Å and with Uiso(H) = 1.2 Ueq(C, N), respectively. The H atom attached to O was found in the electron density map and refined isotropically.

Comment

The syntheses of 8-hydroxyquinoline and its derivatives have attracted interest due to their biological activities and applications in coordination chemistry [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14]. In order to search for new extractants of metal ions and biologically active materials, the title compound was synthesized.

The asymmetric unit of the title compound contains one protonated 8-hydroxy-5-nitroquinolinium cation, one 8-hydroxy-5-nitroquinoline molecule and one perchlorate anion. The two organic moieties are bridged by μ-H atom (cf. the figure). In the crystal structure, the ions and the neutral organic molecule are linked by N—H⋅⋅⋅O and O—H⋅⋅⋅O hydrogen bonds.
