  • Title: Synthesis, crystal structure, and characterization of two metal-quinolone compounds.
    Author: Turel I, Leban I, Klintschar G, Bukovec N, Zalar S.
    Journal: J Inorg Biochem; 1997 May 01; 66(2):77-82. PubMed ID: 9112758.
    Abstract:
    Two novel metal-quinolone compounds have been synthesized and characterized by analytical, spectroscopic, and X-ray diffraction methods. The crystal structure of both, (erxH2) [FeCl4]Cl and (kinoH2)[CuCl4]. H2O, is presented and discussed (erxH2 = doubly protonated form of enrofloxacin, kinoH2 = doubly protonated form of the second quinolone). In both compounds, the hydrogen atom is bonded between the 4-keto oxygen O(1) and carboxylic oxygen O(11), thus preventing the bonding of the metal to this part of the molecule. Antimicrobial activities of metal-quinolone compounds were tested against different microorganisms.
