2. A molecular species consisting of ten vanadium and associated oxygen atoms forming a stable cluster ion common in vanadium chemistry; an important anionic entity in catalysis and analytical chemistry involving multiple metal-oxygen bonds; a polynuclear structure defined by its specific bonding pattern and overall negative charge
3. A chemical entity characterized by a cluster of ten vanadium atoms linked by oxygen atoms creating a decavanadate ion prevalent in inorganic chemistry; a highly structured polyoxometalate ion with unique reactivity and coordination behavior; a multimetal oxide anion recognized for its distinct molecular framework and electronic properties

Etymology: Decavanadate is a compound coinage in chemistry, built from "deca-", the Greek-derived prefix meaning ten, and "vanadate", the name for a salt or ion containing vanadium and oxygen. The prefix counts the vanadium atoms in the ion, which is the feature that gives the term its meaning. Vanadate itself takes its name from vanadium, the metal named after Vanadis, the Norse goddess of beauty, after the chemist who identified it observed its many colors in solution. The "deca-" part works the way it does in many systematic chemical names, where Greek numerical prefixes state how many atoms or groups a molecule contains. Adding it to "vanadate" tells a chemist at once that the ion has a cluster of ten vanadium centers rather than a single one. The ion belongs to the polyoxometalates, a family of metal-oxygen clusters that chemists study for their structures and reactivity.
