The vanadyl ion, [V-O]2+, is distinguished by its symmetry-allowed vanadium-oxo triple bond, a feature that drives the significant resistance of the oxo moiety to protonation by Brønsted acids as well as direct interaction with Lewis acids. In this poster, we will discuss new complexes built upon a Reinhoudt-type heteroditopic ligand framework that enables the study of the vanadyl ion in relatively close proximity to a range of secondary Lewis acidic metal ions. The heterobimetallic complexes can be prepared from a monometallic vanadyl precursor complex via a divergent synthetic strategy. Single-crystal X-ray diffraction analysis confirms the presence of both the vanadyl ion and the secondary metals in the complexes, and infrared spectroscopy provides insight into the influence of the secondary metal ions on the vanadyl moiety. Our latest results will be discussed, including the results of electrochemical studies on these complexes as well as comparative studies with analogous compounds containing the uranyl ion (UO22+).
