Uranyl Incorporation into the Polyoxometalate Cavity. Synthesis and Characterization of [(UO2)8P8W48O184]24
The reaction of uranyl nitrate with the [P 8 W 48 O 184 ] 40– polylacunary polyanion gives the [(UO 2 ) 7 P 8 W 48 O 184 ] 26– ( 1 ) and [(UO 2 ) 8 P 8 W 48 O 184 ] 24– ( 2 ) anions, which were isolated as potassium and ammonium salts. For K 24 [(UO 2 ) 8 P 8 W 48 O 184 ] · 50H 2 O · 3LiCl and (NH 4...
