English The solution behavior of structurally characterized [VVO(OEt)(L)] complexes, which transform into the corresponding divanadium(V,V) compounds [{VVO(L)}₂-μ-O], is reported. Upon controlled potential electrolysis, the corresponding [(L)V₂O₃(L)]⁻ mixed-valence species are obtained upon partial reduction of the [(VVOL)₂-μ-O] formed in solution. All compounds are characterized in the solid state and solution by spectroscopic techniques and DFT calculations. The formation of V₂O₃³⁺ species is confirmed by the observation of a 15- line pattern in the EPR spectra at room temperature.
