| Abstract: | The vibrational spectra of σ-(C3H5)Mn(CO)5 are reported. Assignment of bands is made and carbonyl force constants are calculated. The results indicate that the Mn(CO)5 moiety has C4ν symmetry. The calculated angle between the axial and equatorial carbonyl groups is approximately 95°. The bonding in this compound is very similar to that in (CH3)Mn(CO)5. In the far-infrared region, seven bands are expected in C4ν symmetry (3A1 + 4E), and all are observed. |
