Reaction of the oxidovanadium(IV)-L(N-N) species (L(N-N) is bipy = 2,2'-bipyridine or bipy-like molecules) with either BF4(-) or HF and/or KF results in the formation of compounds of the general formula cis-[V(IV)(═O)(F)(L(N-N))2](+). Structural and spectroscopic (electron paramagnetic resonance) characterization shows that these compounds are in the tetravalent oxidation state containing a terminal fluorido ligand. Density functional theory calculations reveal that the V(IV)-F bond is mainly electrostatic, which is reinforced by reactivity studies that demonstrate the nucleophilicity of the fluoride ligand in a halogen exchange reaction and in fluorination of various organic substrates.
