The reactions of [VIVO(acac)2] (acac = acetylacetonato) with two ONO tridentate ligands, 4-[3,5-bis(2-hydroxyphenyl)-1,2,4-triazol-1-yl]benzoic acid (H2L1, I) and 3,5-bis(2-hydroxyphenyl)-1-phenyl-1,2,4-triazole (H2L2, II) in methanol lead to the formation of the oxidovanadium(V) complexes [VVO(mu-L1)(OMe)]2 (1) and [VVO(mu-L2)(OMe)]2 (2). In the presence of KOH/CsOH, they give the corresponding dioxidovanadium(V) complexes. The isolated complexes K(H2O)[VVO2(L1)] (3), K(H2O)[VVO2(L2)] (4), Cs(H2O)[VVO2(L1)] (5), and Cs(H2O)[VVO2(L2)] (6) along with 1 and 2 have been characterized by various spectroscopic techniques (FTIR; UV/Vis; 1H, 13C, and 51V NMR), elemental analysis, thermal studies, MALDI-TOF MS analysis, and single-crystal analysis of 1a (complex 1 grown together with 4,4?-bipyridyl). The oxidative bromination of thymol, catalyzed by these complexes, in the presence of KBr and HClO4 with H2O2 as an oxidant, gives 2-bromothymol, 4-bromothymol, and 2,4-dibromothymol. The amounts of the catalyst, oxidant, KBr, HClO4, and the solvent were optimized for the maximum conversion of thymol. Both ligands and all complexes were tested in vitro for antiamoebic activity against the HM1:IMSS strain of Entamoeba histolytica by a microdilution method. The complexes are more potent amoebicidal agents than the standard drug metronidazole. Toxicity studies against a human cervical cancer cell line (HeLa) also confirm that these compounds are less cytotoxic than metronidazole.

The new pro-ligand meso-2,2?-(hydroxyimino)dibutyric acid (R,S-H3hidba) has been synthesised from hydroxylammonium chloride and 2-bromobutyric acid. Reaction of H3hidba with [VO(acac)2] (acac = acetylacetonate) yielded the complex [V(R,S-hidba)2]2-1 1, which was crystallised in the presence of Ca2+ ions from H2O as blue tabular crystals. X-Ray crystallography confirmed the same distinctive eight-co-ordinate structure of the complex anion as identified for Amavadin, the form in which vanadium(IV) is bound in Amanita muscaria mushrooms. The crystal structure of 1 contains a network of linked Ca and V centres where the asymmetric unit consists of a Ca2V2 box-like configuration. The Ca and V metal ions are bridged to one another via a series of unidentate and bidentate carboxylate groups from H3hidba, extending throughout the lattice framework. The novel interaction between Ca2+ ions and Amavadin-style complexes has been further illustrated in the crystal structure of [Ca(H2O)5][V(hida)2]·H2O (H3hida = N-hydroxyiminodiacetic acid) 2. The unit cell packing arrangement observed for 2 differs from 1, comprising helical chains formed by alternate Ca and V units linked only by unidentate carboxylate groups. Cyclic voltammetric studies of 1 exhibited a reversible VV-VIV redox couple in H2O (E1/2 = +0.43 V, vs. saturated calomel electrode), this oxidation potential is considerably lower in organic solvents (eg. Me2SO, E1/2 = -0.07 V). The chemical oxidation of 1 in aqueous medium by ammonium ceric nitrate produced a dark red solution which was transferred into CH2Cl2 using [PPh4]Br. From this solution [PPh4][V(R,S-hidba)2] 3 was isolated and studied using 1H, 13C and 51V NMR spectroscopy. The cyclic voltammogram of 3 also displays a reversible VV-VIV redox couple in CH2Cl2 (E1/2 = -0.09 V).

Oxovanadium(IV) and manganese(II) complexes of two Schiff base ligands, bis(2,4-dihydroxyacetophenone)-1,2-propandiimine (H2L1) and bis(2,4-dihydroxyacetophenone)-ethylenediimine (H2L2) were synthesized and characterized. The encapsulation of these complexes in the nanocavities of zeolite-Y was achieved by a flexible ligand method. The prepared heterogeneous catalysts have been characterized by FTIR, NMR and atomic absorption spectroscopy, X-ray diffraction patterns, scanning electron microscopy and BET. The catalytic activities of the encapsulated complexes were studied in the oxidation of alkenes with H2O2 and the reduction of aldehydes with NaBH4. In most cases, the manganese (II) complexes (MnL1-Y, MnL2-Y) showed better activity than the oxovanadium (IV) complexes (VOL1-Y, VOL2-Y) in both oxidation of alkenes and reduction of aldehydes. The catalytic activity of the recovered catalysts was compared with the fresh ones.

The slow-motional ESR analysis appropriate for vanadyl(IV) ions is developed with an accurate treatment of the nonsecular contributions.This results in good agreement between theory and experiments on VO(acac2(pm)) in toluene with axially symmetric magnetic parameters over the whole motional range when a Brownian motion model is used.It is also found that a slightly modified motional narrowing theory based upon the stochastic Liouville equation leads to improved agreement between theory and experiment for VO(acac)2 in toluene which also obeys a Brownian motion model.It is shown that vanadyl slow-tumbling spectra are very sensitive to model (even more so than nitroxides).In particular, experiments on VO(H2O)52+ in aqueous solution are approximately fit by a model of moderate jump, while those on VO(NCS)42- could only be crudely fit by temperature-dependent variations in model.The theory given here is appropriate for any S = 1/2 radical with a single nuclear spin I provided only the high-field approximation is valid, so that nonsecular terms may be treated by a perturbation approach.The effects of (1) angular-dependent transition probabilities and (2) field- vs. frequency-swept spectra upon the slow-motional theory are also discussed.

Molybdenum and tungsten complexes crystallize as mononuclear molecules, whereas the vanadium complex forms dinuclear units. From the complexes, [VO(HLSaltris)]2 shows activity in the oxidation of 4-tert-butylcatechol and 3,5-di-tert-butylcatechol, mimicking the action of the dicopper enzyme catechol oxidase.

A series of dinuclear and mononuclear oxovanadium(V) complexes containing tridentate Schiff base ligands derived from pyridoxal and appropriate thiosemicarbazide or hydrazide are reported. The compounds were characterised by elemental analysis, thermogravimetric analysis, IR and NMR spectroscopy. The molecular structure of the dioxido-vanadium(V) complex [VO2(HL5)]·MeOH·H2O (H2L5 = pyridoxal benzhydrazido ligand), determined by X-ray crystallography, reveals an unexpected distorted trigonal bipyramidal arrangement of the VO2 moiety. A DFT study of this molecule and of the related [VO2(H2L5)] complex of VIV reveals a moderate effect of the oxidation state change on the bond distances and angles, pointing to solvation as the cause of the structural distortion. All complexes were tested as (pre) catalysts for olefin epoxidation by aqueous tert-butylhydroxyperoxide (TBHP) under solvent-free conditions. Low vanadium loadings (0.05% vs. olefin) resulted in good cyclooctene conversions and TOFs. The lifetime of one catalyst was explored through repeated runs with recovery/recycling. DFT calculations have also addressed the olefin epoxidation mechanism, which reveals the possible direct O atom transfer from the activated tert-butoxido (tBuOO-) ligand, without the need to generate a peroxido (O22-) ligand.

Nuclear-electronic interactions are a fundamental phenomenon which impacts fields from magnetic resonance imaging to quantum information processing (QIP). The realization of QIP would transform diverse areas of research including accurate simulation of quantum dynamics and cryptography. One promising candidate for the smallest unit of QIP, a qubit, is electronic spin. Electronic spins in molecules offer significant advantages with regard to QIP, and for the emerging field of quantum sensing. Yet relative to other qubit candidates, they possess shorter superposition lifetimes, known as coherence times or T2, due to interactions with nuclear spins in the local environment. Designing complexes with sufficiently long values of T2 requires an understanding of precisely how the position of nuclear spins relative to the electronic spin center affects decoherence. Herein, we report the first synthetic study of the relationship between nuclear spin-electron spin distance and decoherence. Through the synthesis of four vanadyl complexes, (Ph4P)2[VO(C3H6S2)2] (1), (Ph4P)2[VO(C5H6S4)2] (2), (Ph4P)2[VO(C7H6S6)2] (3), and (Ph4P)2[VO(C9H6S8)2] (4), we are able to synthetically place a spin-laden propyl moiety at well-defined distances from an electronic spin center by employing a spin-free carbon-sulfur scaffold. We interrogate this series of molecules with pulsed electron paramagnetic resonance (EPR) spectroscopy to determine their coherence times. Our studies demonstrate a sharp jump in T2 when the average V-H distance is decreased from 6.6(6) to 4.0(4) A, indicating that spin-active nuclei sufficiently close to the electronic spin center do not contribute to decoherence. These results illustrate the power of synthetic chemistry in elucidating the fundamental mechanisms underlying electronic polarization transfer and provide vital principles for the rational design of long-coherence electronic qubits.
