Vanadium Peroxide Complexes

Synthesis, Characterization and Crystal Structure of a Novel Decavanadate Salt, [V0.50(H2O)5]2[H2(V10O28)]·4(H2O)

“…8 The increasing interest is mainly owing to the role of vanadium in several biological processes such as the regulation of glucose level in the blood of diabetic animals and patients. 3,4,[9][10][11][12][13][14][15][16][17] Moreover, decavanadate and oxovanadates have many biological activities and been successfully used for the comprehension of several biochemical processes. 18 Other interest for vanadium oxides is sourced from their potential uses as secondary cathode materials, both catalysis and electronics.…”

“…18 Other interest for vanadium oxides is sourced from their potential uses as secondary cathode materials, both catalysis and electronics. [19][20][21] Decavanadates, [H n V 10 O 28 ] (6-n)-, are known as predominant polyoxovanadate species in the acidic pH range and also consist of three chemically different vanadium sites; the metal sites at the central junction correspond to two central VO 6 octahedra containing only bridging oxygen atoms, and two types of peripheral vanadium unit including a V=O bond are assembled around the central units. 22 In aqueous medium, under some conditions, the vanadate oligomers may be in equilibrium with monomeric (V 1 ), dimeric (V 2 ) and tetrameric (V 4 ) vanadate species.…”

“…22 In aqueous medium, under some conditions, the vanadate oligomers may be in equilibrium with monomeric (V 1 ), dimeric (V 2 ) and tetrameric (V 4 ) vanadate species. 23 In the literature, the crystal structures of the decavanadate anion, [V 10 O 28 ] 6-, 24 27 ), containing the different transition metal complex cations were characterized. The aim of this research was the synthesis, physicochemical characterization both in the aqueous solution and in the solid state, and the determination of molecular structure of a novel vanadium complex in the presence of chinhydrone.…”

ESI–IT–MS n and DFT calculation for electron affinities of bimetallic oxovanadium complexes

“…These complexes are potentially useful as orally available treatments for diabetes mellitus and are used as catalysts in various oxidation reactions [1][2][3][4][5][6][7][8][9]. Structural characterization of the bimetallic oxovanadium complexes should be a key to the further development of their functions.…”

Electrospray mass spectrometry and tandem mass spectrometry of bimetallic oxovanadium complexes

“…To obtain more information for structural elucidation, three representative bimetallic oxovanadium complexes O xovan ad iu m complexes have played active roles in the fields of pharmaceutical research and organic synthesis. These complexes exhibit attractive promise as orally available treatments for diabetes mellitus and also have a number of applications as catalysts in various oxidation reactions [1][2][3][4][5][6][7][8][9][10]. Recently, some oxovanadium complexes, especially bimetallic oxovanadium complexes of chiral Schiff bases reported by Gong's group, were shown to provide high enantioselectivity for the oxidative coupling of 2-naphthols, which play very important roles in the history of asymmetric synthesis [11][12][13][14][15][16][17].…”
