Step-by-Step Assembly of Trivacant Tungstosilicates: Synthesis and Characterization of Tetrameric Anions

Tungstosilicate building blocks: Two dimeric anions, α‐[{K(H2O)2}Si2W18O66]15−, obtained by self‐association of the monomeric species [SiW9O34]10− upon acidification, can be connected directly (see picture). However, in the presence of silicic acid the anions are linked through an electrophilic [Si4...

Zusammenfassung:Tungstosilicate building blocks: Two dimeric anions, α‐[{K(H2O)2}Si2W18O66]15−, obtained by self‐association of the monomeric species [SiW9O34]10− upon acidification, can be connected directly (see picture). However, in the presence of silicic acid the anions are linked through an electrophilic [Si4O4]8+ ring.
