Ir(TFA)3 (TFA=1,1,1-trifluoro-2,4-pentanedionate) metal complexes with high purity was successfully synthesized. The metal complexes have been characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance spectroscopy. The volatility of metal complexes was studied by thermogravimetry analysis. And a possible decomposition mechanism was studied by mass spectroscopic analysis method. The novel iridium complexes can be severed as precursor in metalorganic chemical vapor deposition of iridium films. iridium films were deposited by metalorganic chemical vapor deposition method, and the Ir(TFA)3 complex was used as precursor. The iridium thin films were characterized by X-ray diffraction and scanning electron microscopy in order to determine crystallinity and surface morphology.
