Theoretical Prediction of Divalent Actinide Borozene Complexes

open access: yesMolecules
The aromatic boron cluster B82– (D7h) has similar π bonding to C6H6, which is named “borozene”. The B82– ligand has been observed to stabilize monovalent Ln(+I) in C7v-LnB8− (Ln = La, Pr, Tb, Tm, and Yb) borozene complexes. Low-valency actinide complexes

Coprecipitation of Ce(III) oxide with UO2

open access: yesJournal of Synchrotron Radiation
The neutralization of acidic solutions containing U (IV) and Ce (III) at room temperature in glove box atmosphere and in the presence of dithionite results in coprecipitation of these elements as amorphous solid solutions CexU1–xO2±y. The solubilities of

Thorium(IV) and Uranium(IV) Complexes with 2,6-Dipicolinoylbis(N,N-diethylthiourea) Ligands

open access: yesMolbank
The reaction of thorium nitrate hydrate with 2,6-dipicolinoylbis(N,N-diethylthiourea), H2Lpic, results in the hydrolysis of the organic ligand and the formation of [Th(2,6-dipicolinolate)2(H2O)4] (1). Hydrolysis can be avoided by the use of [ThCl4(DME)2]

Redox‐Dependent Luminescence in a Pentavalent Uranyl Complex

open access: yesChemistryEurope
The chemistry of pentavalent uranyl is of high interest due to the ion's central role as an intermediate in nuclear separations. However, due to the instability of [UO2]+, little is known about its electronic structure. The synthesis and characterization
