In the title family, the ONO donor ligands are the acetylhydrazones of salicylaldehyde (H2L1) and 2-hydroxyacetophenone (H 2L2) (general abbreviation, H2L). The reaction of bis(acetylacetonato)oxovanadium(IV) with a mixture of tridentate H 2L and a bidentate NN donor [e.g., 2,2?-bipyridine(bpy) or 1,10-phenanthroline(phen), hereafter B] ligands in equimolar ratio afforded the tetravalent complexes of the type [VIVO(L)(B)]; complexes (1)-(4) whereas, if B is replaced by 8-hydroxyquinoline(Hhq) (which is a bidentate ON donor ligand), the above reaction mixture yielded the pentavalent complexes of the type [VVO(L)(hq)]; complexes (5) and (6). Aerial oxygen is most likely the oxidant (for the oxidation of VIV ? VV) in the synthesis of pentavalent complexes (5) and (6). [VIVO(L)(B)] complexes are one electron paramagnetic and display axial EPR spectra, while the [VVO(L)(hq)] complexes are diamagnetic. The X-ray structure of [VVO(L2)(hq)] (6) indicates that H2L 2 ligand is bonded with the vanadium meridionally in a tridentate dinegative fashion through its phenolic-O, enolic-O and imine-N atoms. The general bond length order is: oxo < phenolato < enolato. The V-O (enolato) bond is longer than V-O (phenolato) bond by ?0.07 A and is identical with V-O (carboxylate) bond. 1H NMR spectrum of (6) in CDCl 3 solution indicates that the binding nature in the solid state is also retained in solution. Complexes (1)-(4) display two ligand-field transitions in the visible region near 820 and 480 nm in DMF solution and exhibit irreversible oxidation peak near +0.60 V versus SCE in DMSO solution, while complexes (5) and (6) exhibit only LMCT band near 535 nm and display quasi-reversible one electron reduction peak near -0.10 V versus SCE in CH 2Cl2 solution. The VO3+-VO2+ E 1/2 values shift considerably to more negative values when neutral NN donor is replaced by anionic ON donor species and it also provides better VO3+ binding via phenolato oxygen. For a given bidentate ligand, E1/2 increases in the order: (L2)2- < (L1)2-. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C10H14O5V, you can also check out more blogs about3153-26-2
