  • Interactions of oxovanadium(IV) and the quinolone family member - ciprofloxacin
    Turel, Iztok ...
    The interactions of quinolone ciprofloxacin (cfH) and oxovanadium(IV) were studied by various methods. Green crystals of a complex šVIVO(cf)2(H2O)đ were isolated and the molecular connectivities ... established, although the crystal structure was not perfectly refined due to the instability of the crystals. Based on a plausible interpretation of the data sets, two cf anions bidentately coordinate to a vanadyl cation through carboxylate and carbonyl oxygen atoms; in addition, there is a water molecule in the coordination sphere. Solution techniques (cyclic voltammetry, electronic and electron para`gnetic resonance spectroscopy, potentiometric measurements) coufirmed thepresence of various species in the solution, the composition of which strongly depends on the condifions in the system. The antibacterial activity of the complex against various microorganisms was tested and it was established that its activity is similar to that of free ciprofloxacin.
