Theoretical Prediction of Divalent Actinide Borozene Complexes
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

LANTANIDES (Y, La, Ce, Pr, Nd, Sm) AND ACTINIDS (Th, U) IN SOILS OF THE HIBINO-LOVOZERO PROVINCE
In the Khibinsko-Lovozero district of the Kola Peninsula, the territory is divided into three geochemically different areas. In the background area near Umbozero, both mineral and peated samples contain all rare metals below clark: lanthanides and ...

Coprecipitation of Ce(III) oxide with UO2
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
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
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
