The vanadyl arsenate, VOAsO(4), has been isolated by a solid-state reaction. The structure consists of distorted VO(6) octa-hedra and AsO(4) tetra-hedra sharing corners to build up VAsO(7) layers parallel to ac linked by edge-sharing of VO(6) octa-hedra, forming a three-dimensional framework.

Tetraoctyl-substituted vanadyl phthalocyanine (OVPc4C8) as a new NIR-absorbing discotic liquid crystalline material can form highly ordered thin films with edge-on alignment of the molecules and molecular packing mode identical to that in the phase II of OVPc for solution processed OTFTs with mobility up to 0.017 cm(2) V(-1) s(-1).

Background: It is known that vanadyl compounds are capable of alleviating hyperglycemia in streptozotocin induced diabetic rats. Objective: To examine the effect of vanadyl sulphate (VS) on spermatogenesis of male rats. Methods: Male rats (n=10) were administered 32 mg/kg/day of VS orally and 50 mEq/l NaCl (as drinking water) for one month.  Meanwhile, 11 male rats, the control group, received ...

Vanadyl sulfate (VOSO(4)) is an oxidative form of vanadium that in vitro and in animal models of diabetes has been shown to reduce hyperglycemia and insulin resistance. Small clinical studies of 2- to 4-week duration in type 2 diabetes (T2DM) have led to inconsistent results. To define its efficacy and mechanism of action, 11 type 2 diabetic patients were treated with VOSO(4) at a higher dose (...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...
