ABSTRACT In our work, ciprofloxacin was extracted from the raw material ciprofloxacin hydrochloride and coordinated with the metal ions of copper, manganese and zirconium. The procedures include the comparison of the autoclave method with the solvothermal method, synthesizing the corresponding complexes and conducting antibacterial test on nearly 20 kinds of bacteria. It is shown that under the condition of PH1 and 110℃ - 116℃, the autoclave method and solvothermal method can be utilized to obtain the ciprofloxacin complexes with Cu2+, Mn2+ and Zr2+ as the metal ligands after reacting for 8 hours. The raw material, ligands and monocrystals were characterized by IR, DSC, UV and fluorescence spectrum. Meanwhile a great number of antibacterial tests were carried out, revealing favorable bacteriocidal properties of the resulting complexes.
