New five ciprofloxacin (CIP) complexes of dioxouranium(II), oxozirconium(II), zirconium(IV), oxovanadium(II) and vanadium(IV) in the proportion 1:2 have been prepared using CIP as a drug chelate with UO 2 (NO 3 ) 2 . 6H 2 O, ZrOCl 2 .  8H2 O, ZrCl 4 , VOSO 4 . xH 2 O and V 2 O 5  respectively. The CIP complexes have been characterized based on the elemental analysis, molar conductance, magnetic, (FTIR &amp;  1 HNMR) spectral and thermal studies. The molar conductance studies of the synthesized complexes in DMSO solvent with concentration of 10 –3  M indicate their non-electrolytic properties. At room temperature, the magnetic moment measurements revealed a diamagnetic behavior for all CIP prepared complexes. The different formulas of the new complexes can be represented as [UO 2 (CIP) 2 (NO 3 ) 2 ] ( I ), [VO(CIP) 2 (SO 4 )(H 2 O)] ( II ), [V 2 (O)(O 2 ) 2 (CIP) 2 ] ( III ), [Zr(O)(CIP) 2 (Cl) 2 ] ( IV ), and [Zr(CIP) 2 (Cl) 4 ] ( V ). The thermal analysis data of the complexes indicates the absence of coordinated water molecules except for vanadyl(II) complex ( II ). The CIP chelate is a uni-dentate ligand coordinated to the mentioned metal ion through terminal piperazinyl nitrogen. The transmission electron microscopy (TEM) investigation confirms the nano-structured form of the complexes.
