The metal-carbon bonds in metal carbonyls have both σ and n characters. A σ bond isformed when the carbonyl carbon donates a lone pair of electrons to the vacant orbital ofthe metal. A n bond is formed by the donation of a pair of electrons from the filled metald orbital into the ...

The infrared spectrum of CF 3Mn(CO) 5 has been investigated in the gas phase. The C F stretching bands are found at 1045 and 1063 cm p−1 and the shapes of the band envelopes indicate that these are the frequencies of the e and a 1 modes, respectively. Using these and other data...
Vibrational spectra and bonding in metal carbonyls VI. Evidence for a π-interaction between manganese pentacarbonyl and the perfluoromethyl group The infrared spectrum of CF 3Mn(CO) 5 has been investigated in the gas phase. The C F stretching bands are found at 1045 and 1063 cm p−1 and...
In metal carbonyls, there is synergic bonding interaction between metal and carbon monoxide. This leads to increase in strength of metal ligands bond and decrease in bond order of CO in carbonyl complex as compared to bond order in carbon monoxide. ...

a classification scheme and an approximate energy ordering which does not depend on any point-group symmetry that the cluster may have, and therefore provides a useful framework for discussion of the bonding in cluster compounds such as the boron hydrides and the transition metal cluster carbonyls....
Silylated silicon–carbonyl complexes as mimics of ubiquitous transition-metal carbonyls Silyl-substituted silicon–carbonyl complexes that are stable at room temperature have been prepared by exposure of highly reactive bis(silyl)silylenes to carbon monoxide. The compounds show structural features and reacti...
