Vibrational Study of the Metal-Olefin Bond in 1, 5-Cyclooctadiene Complexes of Rhodium(I), Palladium(II), and Platinum(II)


Journal Article

The infrared and Raman spectra of 1, 5-cyclooctadiene (C8H12) (RhClC8H12)2, PtCl2C8H12, and PdCl2C8H12 have been recorded. Assignments are given for bands I and II, for olefinic CH wagging and rocking modes, and for metal-olefin stretching modes. On the basis of the shift in the frequencies of bands I and II and the CH wagging modes and the frequency of the symmetric metal-carbon stretching modes, the total interaction between the metal and olefin is Rh > Pt > Pd. The shift of the CH rocking modes and the frequency of the asymmetric metal-carbon modes are consistent with the ir interaction going in the order Pt > Rh > Pd with all complexes having extensive π interaction. © 1980, American Chemical Society.
