Abstract
We synthesized and characterized ciprofloxacin-imine complexes, generated from ciprofloxacin and either 4-nitro-1,2-phenylenediamine (NO2PD) or 1,3-propanediamine (PD), in conjunction with zirconyl nitrate dihydrate, sodium molybdate dihydrate, and sodium tungstate dihydrate. Characterization involved numerous analytical methods, containing melting point determination, conductance dimensions, elemental analysis (CHN), metal content determination (%), infrared, electronic spectra, nuclear magnetic resonance, and mass spectrometry. Our findings reveal that the ligand as functions a tetra-dentate chelate binding to metal ions via azomethine and deprotonated carboxylate group. Additionally, the complexes and ligands were tested in contradiction of two types of bacteria (Staphylococcus aureus, Bacillus subtilis) and all prepared compounds showed good spectrum activity.
