A vanadyl(iv) complex, K2V(O)(dtoym)2, forms polymeric interactions via intermolecular dative bonds; the intermolecular dative interaction is tuned by changes of the ligand planarity and counter cations of the vanadyl complex.

Diabetes mellitus (DM), closely related to diabetic nephropathy, is one of the major public health problems worldwide. Today, with increasing understanding underlying pathophysiology DM, new oral anti-diabetic treatment strategies are being developed. Vanadium a transition element that widely distributed in nature, and its administration has been reported improve DM humans variety animal models...

Cross-linking of the cubic silicate building block, Si8O20 with vanadyl chloride leads to porous solids in which a homogeneous dispersion of isolated vanadyl groups is maintained throughout the matrix even at high loadings of vanadium.

Background: There is not any in vivo studies that shows inducing of euglycemia by vanadyl is independent from plasma insulin.  Therefore in the present study we planned to investigate the antidiabetic effects of vanadyl in diabetic rats. Materials and Methods: Rats became severely diabetic by an IV injection of 50-55mg/kg streptozotocin (STZ), 15 days after the injection, the blood glucose of ...

Shewanella oneidensis couples anaerobic oxidation of lactate, formate, and pyruvate to the reduction of vanadium pentoxide (V(V)). The bacterium reduces V(V) (vanadate ion) to V(IV) (vanadyl ion) in an anaerobic atmosphere. The resulting vanadyl ion precipitates as a V(IV)-containing solid.

Vanadium ion is toxic to animals. However, vanadium is also an agent used for chemoprotection against cancers in animals. To understand both the toxic and beneficial effects we studied vanadium distribution in rats. Accumulation of vanadium in the liver nuclei of rats given low doses of compounds in the +4 or +5 oxidation state was greater than in the liver nuclei of rats given high doses of va...

Vanadyl ions (V0 2 + ) occur coordinated to other groups both in solids and liquids, bringing the total coordination to five or six. Usually the metal ion is surrounded by a distorted octahedron of oxygen ligands. However, the behaviour of the unpaired electron in the vanadyl complexes is dominated by the strong V = 0 bonding; as a result, most of the complexes possess very nearly a square pyra...
