Vanadium nuclear quadrupole coupling constants are sensitive to the coordination geometry of the vanadyl ion, and thus sensitive to the structural distortions within this series of complexes. (51)V ESE-ENDOR has been shown to be a probe of the coordination geometry of vanadyl complexes. Such a spectroscopic probe should prove useful in the investigation of vanadyl of unknown coordination geometry, such as may be found in the interaction of the vanadyl ion with biomolecules.}, number={26}, journal={INORGANIC CHEMISTRY}, author={Grant, CV and Geiser-Bush, KM and Cornman, CR and Britt, RD}, year={1999}, month={Dec}, pages={6285–6288} }

Electrochemical studies indicate that the metal centers in 1 are strongly coupled (Kcom ≈ 105). The corresponding sulfoxide, H2mbp2SO, coordinates to vanadium(V) to form a six-coordinate complex with a 2:1 L:M stoichiometry. Under the conditions of this study, direct oxygenation of the coordinated sulfide in 1 and 2 has not been observed.
