Nov 5, 1997 · Vanadate Encapsulated Polyoxoborate Framework with [V12B18] Clusters: An Efficient Bifunctional Electrocatalyst for Oxygen and Hydrogen Evolution Reactions.

The [V 18 O 42 (PO 4 )] 11- anion has a superkeggin structure with a PV 12 O 40 Keggin unit capped by six VO moieties which lie above six rectangle faces of the T d -distorted cuboctahedron defined by …

From kinetic studies of 18 O-exchange between aqueous solutions of K 12 V 18 O 42 · 16H 2 O and water it is concluded that [V 18 O 42] 12− exists as a discrete ion in this medium.

Herein, a polyoxovanadate, K 12 [V 18 O 42 (H 2 O)]∙6H 2 O (V18), was prepared and characterized. The anti-tumor activities of V18 against MCF-7 cells were investigated in vitro using MTT assays. …
