چکیده
A follow up to an earlier review on the coordination and extraction of trivalent actinide lanthanide ions with triazinylpyridine N-donor ligands is presented. It reviews recent development in fields ligand modifications improvements, considering both hydrophobic compounds (to be used as extracting agents) hydrophilic stripping agents), a focus fundamental studies.

Lanthanide/actinide differentiation with sterically encumbered N-heterocyclic carbene ligands.
A study is reported on the relative stability of trivalent bis(ligand) complexes of the form [M(L(R))(2)N''] for trivalent group 3, lanthanide and actinide cations, using the sterically demanding N-heterocyclic carbene ligand L(R) = [OCMe(2)CH(2){CNCH(2)CH(2)NR}] (R = (i)Pr L(P), Mes L(M), Dipp L(D); N'' = N(SiMe(3))(2)). For the small Y(III) cation (r(6-coord) = 1.040 A) and the smallest L(R),...
متن کاملDensity functional theory investigations of the trivalent lanthanide and actinide extraction complexes with diglycolamides.
At present, designing novel ligands for efficient actinide extraction in spent nuclear fuel reprocessing is extremely challenging due to the complicated chemical behaviors of actinides, the similar chemical properties of minor actinides (MA) and lanthanides, and the vulnerability of organic ligands in acidic radioactive solutions. In this work, a quantum chemical study on Am(III), Cm(III) and E...
متن کاملLanthanide speciation in potential SANEX and GANEX actinide/lanthanide separations using tetra-N-donor extractants.
Lanthanide(III) complexes with N-donor extractants, which exhibit the potential for the separation of minor actinides from lanthanides in the management of spent nuclear fuel, have been directly synthesized and characterized in both solution and solid states. Crystal structures of the Pr(3+), Eu(3+), Tb(3+), and Yb(3+) complexes of 2,9-bis(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzotriaz...
متن کاملTrivalent lanthanide compounds with fluorinated thiolate ligands: Ln-F dative interactions vary with Ln and solvent.
The fluorinated tris-thiolate compounds Ln(SC(6)F(5))(3) can be isolated as THF, pyridine, or DME coordination complexes. In THF, the larger Ce forms dimeric [(THF)(3)Ce(SC(6)F(5))(3)](2) (1) with bridging thiolate ligands, while the smaller lanthanides (Ln = Ho (2), Er (3)) form monometallic (THF)(3)Ln(SC(6)F(5))(3) compounds. There is a tendency for fluoride to coordinate to Ln throughout the...

Direct reactions between copperIJI) halides, thioacetamide (TAA) and 4,4′-bipyridine (4,4′-bpy) or pyrazine (pyz) in MeCN led to the formation of mixed ligand compounds [Cu2Cl2IJTAA)2IJ4,4′-bpy)]n (1), [Cu2X2IJTAA)4IJ4,4′-bpy)]·(4,4′-bpy) (X = Cl (2), Br (3) and I (4)) and [Cu2Cl2IJTAA)2IJpyz)]n (5), and the binuclear complex [Cu2I2IJTAA)4] (6). The formation of these compounds strongly depends...
