Abstract: The reaction of SiW9O3410-and GeW9O3410-with metal cations leads to Keggin trisubstituted polyoxoanions. Areview of all known trisubstituted Keggin anions demonstrates characteristic patterns of 183WNMR chemical shifts.

Key words: Trivacant heteropolyanion, Trisubstituted polyoxometalate, 183WNMR spectrum, Liquid secondary ion mass spectra
