Synthesis, molecular structure and chemical properties of a new tungstosilicate with an open Wells–Dawson structure, α-[Si2W18O66]16−
Abstract
Acidification of K10A-α-[SiW9O34] in aqueous solution leads to the formation of α-[Si2W18O66]16−, built up from two A-α-{SiW9O34} subunits, which reacts with metal
