Synthesis and characterization of a new Keggin anion containing Be

The paper of researchers from NIIC SB RAS is published in Chemical Communications (IF 6.718):

The first Keggin-type Be-containing heteropolyanion [BeW₁₂O₄₀]⁶⁻ (1⁶⁻) has been obtained by hydrothermal synthesis from sodium tungstate and Be(NO₃)₂. It was crystallized as (Bu₄N)_4.8Na_1.2[BeW₁₂O₄₀] (1a) and (Me₂NH₂)₆[BeW₁₂O₄₀]·4H₂O (1b) salts, which were characterized by ⁹Be and ¹⁸³W NMR, ESI-MS, CV, and single crystal X-ray diffraction analysis.
