Cu(II) and Zn(II) complexes with a fluoroquinolone antibiotic: Spectroscopic and X-ray absorption characterization
摘要:
The synthesis of two complexes with the antibiotic flumequine, [Cu(Flumequine)(2)(OH2)(2)] (1) and [Zn(Flumequine)(2)(OH2)(2)]center dot H2O (2) is reported. Their molecular structure was elucidated by combining various spectroscopic techniques. The EPR parameters combined with XAS data underline a tetragonal distorted octahedral geometry for the two complexes. The coordination occurs through the carbonyl and carboxylate oxygen atoms in the equatorial plane. The coordination sphere is completed by two water molecules in axial position.
