Vibrational spectra of η5-cyclopentadienyldicarbonyl(thiocarbonyl)-manganese(I) and η5-cyclopentadienylcarbonyl(dithiocarbonyl)-manganese(I)

Abstract

The ir and laser Raman spectra of η5-C5H5Mn(CO)2(CS) and η5-C5H5Mn(CO)(CS)2 have been investigated. In the case of the monothiocarbonyl complex, vapor phase, solution, and solid-state measurements were made, while for the dithiocarbonyl, only solid-state data were obtained. The vibrational spectra of both complexes have been assigned satisfactorily in terms of the C5v and Cs local symmetries of the η5-C5H5—Mn and Mn(CO)2(CS) (or Mn(CO)(CS)2) moieties, respectively. The effect of change of state on the spectra of the monothiocarbonyl complex is discussed.
