Synthesis and characterization of a new Keggin anion: [BeW 12 O 40 ] 6
The first Keggin-type Be-containing heteropolyanion [BeW 12 O 40 ] 6− (1 6− ) has been obtained by hydrothermal synthesis from sodium tungstate and Be(NO 3 ) 2 . It was crystallized as (Bu 4 N) 4.8 Na 1.2 [BeW 12 O 40 ] ( 1a ) and (Me 2 NH 2 ) 6 [BeW 12 O 40 ]·4H 2 O ( 1b ) salts, which were charact...
