B-α-[AsW9O33]9- polyoxometalates incorporating hexanuclear uranium {U6O8}-like clusters bearing the UIV form or unprecedented mixed valence UIV/UVI involving direct UVI=O-UIV bonding

Résumé

The use of B-α-[AsW9O33]9-anionic moieties in association with the tetravalent 5f uranium UCl4 precursor affords three new hexanuclear uranium {U6O8}-like clusters embedded in a polyoxometalate architecture. Two of them are constituted by an unprecedented uranium mixed valence UIV/UVI
