Vanadium(V) oxide arsenate(V), VOAsO4
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.
متن کاملThe vanadium Magnéli phases V
To compare the metal-insulator transitions (MITs) of VO2 and V2O3 we analyze the relations between the structural and electronic properties of the vanadium Magnéli phases. These materials set up the homologous series VnO2n−1 (3 ≤ n ≤ 9) and have crystal structures comprising typical dioxide-like and sesquioxidelike regions. As the MITs of the vanadium Magnéli phases are accompanied by structura...
متن کاملDetermination of the Stability Constant of Vanadium (V) with Alaine
Formation equilibria of dioxy vanadium (V) complex with alanine in acidic media (pH<2.3) has been investigated potentiometrically and spectrophotometrically. In this condition the 1:1 complex has the formula VO2Y, where Y¯ represent the fully dissociated aminocarboxylate anion. The stability constant of VO2Y was determined as log KVO2Y=11.32±<e...
