Insights into the Complexation Mechanism of a Promising Lipophilic PyTri Ligand for Actinide Partitioning from Spent Nuclear Fuel

Autor: Francesco Galluccio, Elena Macerata, Patrik Weßling, Christian Adam, Eros Mossini, Walter Panzeri, Mario Mariani, Andrea Mele, Andreas Geist, Petra J. Panak

Publikováno v: Inorganic Chemistry, 61 (46), 18400–18411

The challenging issue of spent nuclear fuel (SNF) management is being tackled by developing advanced technologies that point to reduce environmental footprint, long-term radiotoxicity, volumes and residual heat of the final waste, and to increase the

Spectroscopic investigation of the covalence of An( iii ) complexes with tetraethylcarboxamidopyridine

Autor: Thomas Sittel, Patrik Weßling, Dennis Großmann, Eliane Engels, Andreas Geist, Petra J. Panak

Publikováno v: Dalton Transactions, 51 (20), 8028–8035

M(iii)–O and M(iii)–N interaction in [M(Et-Pic)3]3+ (M = Ln and Am; Et-Pic: N,N,N′,N′-tetraethyl-2,6-carboxamidopyridine) complexes were studied. NMR and TRLFS data suggest an increased partial covalent interaction in the An(iii)–N bond.
