Theoretical treatments of the distorted square pyramidal co‐ordination observed in vanadyl β‐keto‐enolates predict restricted interligand conjugation and minimal π‐interaction in the oxovanadium‐ligand bonds. The effects of ligand substitution on the vibrational and electronic spectra of vanadyl β‐keto‐enolates yield evidence that strong σ‐bonding and ionic contributions are chiefly responsible for the strong vanadium‐ligand bonding.
