Abstract: Salts of the title anions have been prepared from the lacunary tungstates α- and β-SiW9O3410- and characterized by elemental analysis, spectroscopy, polarography.Tungsten-183 NMRspectra of the title complexes consist of two lines (intensity ratio 2:1) as expected for the C3Vstructure of trisubstituted α- and β-Keggin anions.

Key words: Trisubstituted Keggin structure, Heteropolyanions, Heteropolytungstate containing 3A group elements
