Synthesis, characterization, reactivity, and catalytic potential of model vanadium(IV, V) complexes with benzimidazole-derived ONN donor ligands.
Reaction between [VO(acac)(2)] and the ONN donor Schiff base Hsal-ambmz (I) (Hsal-ambmz = Schiff base obtained by the condensation of salicylaldehyde and 2-aminomethylbenzimidazole) resulted in theExpand
51V solid-state magic angle spinning NMR spectroscopy and DFT studies of oxovanadium(V) complexes mimicking the active site of vanadium haloperoxidases.
A series of 11 oxovanadium(V) complexes mimicking the active site of vanadium haloperoxidases have been investigated by (51)V magic angle spinning NMR spectroscopy and density functional theoryExpand
Synthesis, characterisation and catalytic potential of hydrazonato-vanadium(V) model complexes with [VO]3+ and [VO2]+ cores.
Reaction between [VO(acac)2] and H2L (H2L are the hydrazones H2sal-nah I or H2sal-fah II; sal = salicylaldehyde, nah = nicotinic acid hydrazide and fah = 2-furoic acid hydrazide) in methanol leads toExpand

Binuclear, mu-bis(oxo)bis{oxovanadium(V)} complexes [(VOL)2(mu-O)2](2 and 7)(where HL are the hydrazones Hacpy-nah I or Hacpy-fah II; acpy = 2-acetylpyridine, nah = nicotinic acid hydrazide and fah =Expand
Interaction of vanadyl (VO2+) with ligands containing serine, tyrosine, and threonine.
Reaction of vanadyl sulfate with an aldehyde (2-hydroxy-1-naphthaldehyde (nap); 3-methoxysalicylaldehyde = o-vanillin (van)) and an amino acid carrying an OH group (L-tyrosine (L-tyr); L-serineExpand
Vanadium(IV and V) Complexes Containing SNO (Dithiocarbonylhydrazone; Thiosemicarbazone) Donor Sets
The VO2+ complexes [VOCl(ONS)] (3) and [VO(ONS)′] (4), and the VO3+ complexes [VO(OEt)(ONS)′] (5) {ONS = (R)-salicylaldehyde thiosemicarbazonate(1−) R = 5,6-C4H4 (3a) or 3-OMe (3b); (ONS)′ =Expand
Modeling the active site structures of vanadate-dependent peroxidases and vanadate-inhibited phosphatases
The active center of vanadate-dependent peroxidases (VPOs) is represented by vanadate covalently attached to a histidine, with vanadium in a trigonal-bipyramidal environment. Protein phosphatases andExpand
Molecular assembly of novel hetero-metal clusters: [(O=MoS 3 Cu 2 ) 2 (μ-Sn 2 S 6 )] 4− and [(S=MoS 3 Cu 2 ) 3 (μ 3 -S) 2 ] 4−
Abstract Two mixed molybdenum–copper–sulfur clusters containing two or three {E=MoS3Cu2} (E=O, S) fragments have been assembled around the nucleophiles μ2-Sn2S64− or μ3-S2−, viz.Expand
Vanadium complexes with enamines having tyrosine constituents
Abstract Four new oxovanadium(IV)-complexes of Schiff-base ligands with tyrosine constituents have been synthesised and characterised. The crystal and molecular structures ofExpand
Role of the alkali metal ion and hydrogen bonds in M[VO(O2)2bpy] · nH2O (M = Li+, Na+, K+ and Rb+) and Cs[VO(O2)2bpy] · H2O2 complexes: The X-ray crystal structures and spectroscopic properties
Abstract Both V2O5 and MVO3, were used for the synthesis of the M[VO(O2)2bpy] · nH2O · mH2O2 complexes (M = alkali metal ion, bpy = 2,2′-bipyridine). The method with MVO3 was found to be moreExpand
