The first Keggin-type Be-containing heteropolyanion [BeW12O40](6-) (1(6-)) has been obtained by hydrothermal synthesis from sodium tungstate and Be(NO3)2. It was crystallized as (Bu4N)4.8Na1.2[BeW12O40] (1a) and (Me2NH2)6[BeW12O40]·4H2O (1b) salts, which were characterized by (9)Be and (183)W NMR, ESI-MS, CV, and single crystal X-ray diffraction analysis.
