The syntheses of monomeric complexes of V(III) and V(IV) containing the ligands 1,4,7-triazacyclononane (L) and its N-methylated derivative L′ are reported: [LVF₃] · 0,5 H₂O; [L′VF₃]·4H₂O; [L′V(acac)Cl]PF₆; [LVOF₂] · 2 H₂O; [L′VO(acac)](ClO₄). The crystal structures of [L′VF₃]·4H₂O and of [L′VO(acac)](ClO₄) have been determined by X-ray crystallography. Electronic spectra, magnetic properties and the electrochemistry of these complexes are reported.
