“…In one hand, the utilization of polyvacant anionic precursors with actinides(IV) was reported later in aqueous solution in 1999 and more recently their X-Ray diffraction structure determinations were described from 2015. [41][42][43][44][45] As expected, the actinide cation exhibited a typical Archimedean square antiprismatic geometry. This study was then completed by using other transuranian elements Pu(IV), Am(III), Cm(IV) and Cf(IV), for which molecules of general formula [An (IV,III) (XW 11 O 39 ) 2 ] n-, were identified in aqueous solution.…”

“…Il est à noter que ces composés peuvent être non protonés [2,5,6,10,[12][13][14], monoprotoné [4] ou diprotonés pour quelques terres rares [7,8,11,[15][16][17], et même triprotoné dans le cas de samarium(III) [9]. Cet environnement antiprisme d'Archimède est également attribué à l'uranium(IV) dans les polyanions [U IV (XW 11 O 39 ) 2 ] 10-(X = B, Si, Ge, P V , As V ) [18][19][20][21][22], [U IV (X 2 W 17 O 61 ) 2 ] 16-(X = P V , As V ) [18,[22][23][24]. Par la suite, des composés mixtes dissymétriques renfermant le ligand W 5 ] 11-, constitue l'objet de cette note.…”
