Infrared intesities of the carbonyl stretching modes in bipyramidal cobalt and iron tetracarbonyl compounds Academic Article uri icon

abstract

  • The dipole moment derivatices for the carbonyl strectching modes in monosubstituted (c3v tribonal bipyramidal metal carbonyls have been calculated assuming that each carbonyl stretching mode exhitits a characteristic MCO group moment derivative. The intensity distribution in the two A1 modes is discussed in terms of coupling, the angle (θ) between axial and equatorial CO groups. and electron migration along the threefold axis during the vibrations. Equations for calculating the dipole moment derivatices for the A1 (equatorial) moment derivative is expressed as a function of the angle(θ) and the electronic migration parameter (ρ{variant}) and is represented graphically. The compound considered in this study are Cl3SiCo(CO)4, (C6H5)3SiCo(CO)4and(C6H5)3PFe(CO)4. © 1970.
