Sažetak
The complexation of ZnII ions with quinolone in aqueous solution depends mainly upon pH. To investigate the pH dependence of the complexation between ZnII and the quinolone derivative Ciprofloxacin (abbreviation cfH), UV-Vis spectroscopy was used. The crystal structure of the compound [C17H19N3O3F]2 ⋅ [ZnCl4] ⋅ 2H2O (compound I) was determined by X-ray diffraction, which showed the structure to be ionic, consisting of a tetrachlorozincate(II) dianion and two protonated, monocationic Ciprofloxacin molecules. Compound II ([Zn(cf)2] ⋅ 3H2O) was obtained as microcrystals from an aqueous solution of Ciprofloxacin hydrochloride and zine sulphate adjusted to pH = 8 by the addition of sodium hydroxide. Both complexes were characterized by elemental analysis, mass speetrometry, TG analysis and IR spectroscopy. From the analysis of these results we have proposed a probable mode of bonding for the complexation of ZnII to Ciprofloxacin in compound II.
