WebDoes the fact that the carbonyl peak in the enol form is hydrogen bonded change its shift? Assuming the only contribution to the lowering of the $\ce{C=O}$ stretching frequency is conjugation to the one $\ce{C=C}$ bond, this would lower the peak to ~$\pu{1655 cm^{-1}}$: Surely this would be seen as a peak in its own right? WebHowever, acetylacetonate is a stronger ligand that displaces the water molecules. Since Vanadium is bonded to oxygen with a V=O bond, only 2 acetylacetonate will only be able to form coordinate bond with the vanadium central metal ion to form the VO (acac)2 complex with a square pyramidal geometry as shown in Figure 3.
