Abstract

Binuclear mixed valence oxovanadium(IV/V) complexes of general formula [V2O3L] containing a [OVIV(mu-O-oxo)-(mu-O-phen)(VO)-O-V](2+) core have been synthesised using conformationally labile N4O3-coordinating heptadentate ligands (H3L). The X-ray structure of one complex has been examined. Solution EPR spectra revealed that the impaired electron of the complexes is delocalised between the two vanadium centres. The simulated EPR spectrum of one complex confirms this experimental observation. DFT studies have been performed using crystallographic coordinates in order to obtain further insight into the electronic structure of this type of molecule.
