Abstract: | IR and Raman spectra of [Mo2O2S2(S2)2]2- were reported. The resonance Raman spectra and the depolarization ratios in CH3CN solution were measured. By using the data of crystal structure, the simplified normal coordinate calculation of the stretching vibrations for anion [Mo2O2S2(S2)2]2- was performed. The results obtained are useful to assign the vibrational bands of some Mo-Fe-S clusters. |
