Synthesis, Characterization and Thermoanalytical Studies of Neodymium Norfloxacinate

Abstract

: The neodymium complex with the ligand norfloxacin was synthesized in the solid state. Characterization and thermal behavior of the compounds were performed employing X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR) and Simultaneous Thermogravimetry/Derivate Thermogravimetric-Differential Thermal Analysis (TG/DTG-DTA). From the TG/DTG-DTA curves, it was possible to determine the minimum formula ([Nd(Nor)3]6H2O), thermal stability and thermal decomposition steps. XRD showed that the complex was obtained with low crystallinity and analysis of the main bands of the IR spectrum it was possible to suggest the probable sites of coordination of the ligand to the neodymium ion.
