Syntheses and Spectroscopic Studies of Metal-Metal Bonded Complexes (Zr-Fe)

摘要

The preparation of the metal-metal bonded complex Cp2ZrClFeCp(CO)2 has been achieved by the reaction of Cp2ZrCl2 and strong nucleophile NaFeCp(CO)2. The more soluble metal-metal bonded complexes Cp2ZrRFeCp(CO)2(R = CH3, n-C8H17) have also been prepared through the reaction of Cp2ZrRCl and NaCpFe(CO)2. The complexes were characterized by IR, Raman, 1H NMR and Mass spectra. The complete absorption (100-3800 cm-1) spectra for the three metal-metal bonded molecules are reported and the bands of each vibration were assigned.
