Controlled reductive assembly of capped Keggin anions [PMo 12 O 40 (ML m ) n ] 3 has been achieved by reduction of [PMo 12 O 40 ] 3 with sodium-mercury amalgam in the presence of metal halides, as exemplified by the rational syntheses of mono-capped [PMo 12 O 40 {Co(MeCN) 2 }] 3 and bi-capped [PMo 1...

Description
Summary:Controlled reductive assembly of capped Keggin anions [PMo 12 O 40 (ML m ) n ] 3 has been achieved by reduction of [PMo 12 O 40 ] 3 with sodium-mercury amalgam in the presence of metal halides, as exemplified by the rational syntheses of mono-capped [PMo 12 O 40 {Co(MeCN) 2 }] 3 and bi-capped [PMo 12 O 40 (VO) 2 ] 3 and [PMo 12 O 40 Sb 2 ] 3 . Mild, non-aqueous reductive aggregation provides controlled access to a range of soluble, electron-rich capped polyoxometalates based on the {PMo 12 O 40 } Keggin structure, with capping groups from across the periodic table.
