Sodium metatungstate
Hello everyone!
Not very long ago I saw a fairly interesting ion: [H2W12O40]6-. I tried searching all over the internet, but couldn't find any relatable method of
preparing this compound. Has anyone here tried synthesising it? Is it possible to use [WO4]2- as a reagent?

Hi!
This paper, and its references, is perhaps a good starting point:
Solid state chemistry of polytungstic acids and their salts.
In summary, and probably massively over-simplifying:
Electrolyse a sodium tungstate solution, and then add a chloride salt to get the metatungstate you desire.
