Reaction of [VO(acac)2](where acac = acetylacetonate), benzohydroxamic acid (Hbha), and two similar aroylhydrazone ligands in methanol produced two benzohydroxamate-coordinated mononuclear vanadium(V) oxo complexes with general formula [VOL(bha)], where L = L1 = N?-(5-bromo-2-hydroxybenzylidene)-2-fluorobenzohydrazide (H2L1), and L = L2 = N?-(3-bromo-2-hydroxybenzylidene)-2-fluorobenzohydrazide (H2L2). Crystal and molecular structures of the complexes were determined by single crystal X-ray diffraction method. All of the investigated compounds were further characterized by elemental analysis, and FT-IR and UV-Vis spectroscopy. Single crystal X-ray structural studies reveal that the V atoms in both complexes are in octahedral coordination with the benzohydrazone ligands coordinated to the VOcores through phenolate O, imino N, and enolate O atoms, and the benzohydroxamate ligands coordinated to the VO cores through deprotonated hydroxyl O and carbonyl O atoms. Thermal stability of the complexes was studied.

Homo- and hetero-dinuclear nickel(II), copper(II), and oxidovanadium(IV) complexes of a Schiff-base-fused phthalocyanine (pc) with bulky substituents, 2,6-dimethylphenoxy and t-butyl groups, were prepared and characterized. The introduced salen-like Schiff-base unit was shown to affect the spectral feature based on the pc unit in the near infrared region, the Q band being widely split over 600-800 nm. A fairly large ferromagnetic interaction (J = 6.0 cm -1) was observed for the CuII(pc)-CuII(salen) homo-dinuclear complex, while an antiferromagnetic interaction (J = -3.2 cm -1) was observed for the CuII(pc)-VIVO(salen) hetero-dinuclear complex.

New oxidovanadium(IV) complexes with a modification of the ligand in the VO2+ coordination sphere were synthesized. [VO(mIDA)(dmbipy)]?1.5H2O and [VO(IDA)(dmbipy)]?2H2O were obtained as dark green crystals and grey-green powder, respectively (mIDA = N-methyliminodiacetic anion, IDA = iminodiacetic anion, dmbipy = 4,4?-dimethoxy-2,2?-dipyridyl). The crystal structure of [VO(mIDA)(dmbipy)]·1.5H2O has been determined by the X-ray diffraction method. The studies of structure of [VO(mIDA)(dmbipy)]?1.5H2O have shown that this compound occurs in the crystal as two rotational conformers. Furthermore, the stability constants of [VO(mIDA)(dmbipy)]?1.5H2O and [VO(IDA)(dmbipy)]?2H2O complexes in aqueous solutions were studied by using the potentiometric titration method and, consequently, determined using the Hyperquad2008 program. Moreover, the title complexes were investigated as antioxidant substances. The impact of the structure modification in the VO2+ complexes on the radical scavenging activity has been studied. The ability to scavenge the superoxide radical by two complexes – [VO(mIDA)(dmbipy)]·1.5H2O and [VO(IDA)(dmbipy)]·2H2O was studied by cyclic voltammetry (CV) and nitrobluetetrazolium (NBT) methods. The title complexes were also examined by the spectrophotometric method as scavengers of neutral organic radical – 1,1-diphenyl-2-picrylhydrazyl (DPPH?) and radical cation – 2,2′-azinobis-(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS?+). Furthermore, the biological properties of two oxidovanadium(IV) complexes were investigated in relation to its cytoprotective properties by the MTT and LDH tests based on the hippocampal HT22 neuronal cell line during the oxidative damage induced by hydrogen peroxide. Finally, the results presented in this paper have shown that the both new oxidovanadium(IV) complexes with the 4,4?-dimethoxy-2,2?-dipyridyl ligand can be treated as the cytoprotective substances.

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-.

The rather unusual schiff base N,N’-bis(benzamido)acetylacetoneimine reacts with lead(II), zinc(II), cadmium(II), oxovanadium(IV) and platinum(II) salts to provide complexes of the type , , .2H2O, and respectively.The complexes are sparingly soluble in water and common organic solvents.They behave as non-electrolytes in nitromethane.In all these complexes the ligand functions as a dibasic ONNO quaridentate schiff base.The oxovanadium(IV) complex is paramagnetic (mu = 1.7 B.M.).The infrared spectra of the ligand and the complexes indicate that the ligand coordinates in the enol form.The nuC=O and the nuNH modes of the free ligand at 1660 and 3280 cm-1 respectively are absent in all the complexes.The complex probably has a square-pyramidal structure with the lone pair occupying the apex of the square-pyramid.

The dinuclear V(V) complexes (VOL)2O (L = SAE (1), SAMP (2), SAP (3)) have been synthesized from VO(acac)2 and the corresponding tridentate ligands LH2 in methanol under reflux conditions and subsequent air oxidation in organic solvent.
