Tungstosilicate building blocks : Two dimeric anions, α‐[{K(H 2 O) 2 }Si 2 W 18 O 66 ] 15− , obtained by self‐association of the monomeric species [SiW 9 O 34 ] 10− upon acidification, can be connected directly (see picture). However, in the presence of silicic acid the anions are linked through an electrophilic [Si 4 O 4 ] 8+ ring.
