“…For UO 2 (sf) 2 , only the enantiomers having the two uranyl oxygen atoms at trans position have been constructed as starting models (Scheme S5) in accordance with the structure of all the uranyl(VI) complexes reported in the literature [33][34][35]. After the Langevin dynamics simulated annealing calculations, the total energy results of 20 different conformations for each starting model have been obtained (Table S10) with almost average energy, as expected [52].…”

“…For all the metal ions a default parameter set with R * = 2.20 Å and e * = 0.02 kcal mol À1 was used, since the van der Waals interactions are not expected to play a major role in such bonded representations as in octahedral complexes. Metal-ligand bond lengths were corrected in the final models using harmonic restraints with equilibrium values extracted from crystallographic data of similar compounds [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] (Tables S1, S3, S5, S7, S9). Non-bonded interactions were calculated in vacuo with no cutoff and the electrostatic energy term was treated using bond dipoles.…”

“…Many such studies [3][4][5][6] were motivated by the awareness that an enhanced understanding of the complexation behaviour of this ion has implications for the winning, processing and use of uranium as well as for the appropriate control, processing and storage of nuclear wastes [7][8][9][10][11][12][13][14][15][16]. As a consequence, a number of studies have focused on ligand design for selective uranium uptake [17][18][19][20], with particular studies focused on the separation of actinides from the lanthanides [21][22][23][24][25] -metals which occur together in nature and nuclear wastes.…”

“…As far as we are aware, this is a first attempt to summarize and discuss the synthetic and structural chemistry, the properties and the potential applications of dinuclear and oligonuclear An complexes based on Schiff-based ligands. The topic has been partly covered in some older, excellent reviews or book chapters dealing with the chemistry of actinoids [2][3][4][5][6][7][8][9][10] and the coordination chemistry of Schiff bases [11].…”

Even 155 years after their first synthesis, Schiff bases continue to surprise inorganic chemists. Schiff-base ligands have played a major role in the development of modern coordination chemistry because of their relevance to a number of interdisciplinary research fields. The chemistry, properties and applications of transition metal and lanthanoid complexes with Schiff-base ligands are now quite mature. On the contrary, the coordination chemistry of Schiff bases with actinoid (5f-metal) ions is an emerging area, and impressive research discoveries have appeared in the last 10 years or so. The chemistry of actinoid ions continues to attract the intense interest of many inorganic groups around the world. Important scientific challenges are the understanding the basic chemistry associated with handling and recycling of nuclear materials; investigating the redox properties of these elements and the formation of complexes with unusual metal oxidation states; discovering materials for the recovery of trans-{UVIO2}2+ from the oceans; elucidating and manipulating actinoid-element multiple bonds; discovering methods to carry out multi-electron reactions; and improving the 5f-metal ions’ potential for activation of small molecules. The study of 5f-metal complexes with Schiff-base ligands is a currently “hot” topic for a variety of reasons, including issues of synthetic inorganic chemistry, metalosupramolecular chemistry, homogeneous catalysis, separation strategies for nuclear fuel processing and nuclear waste management, bioinorganic and environmental chemistry, materials chemistry and theoretical chemistry. This almost-comprehensive review, covers aspects of synthetic chemistry, reactivity and the properties of dinuclear and oligonuclear actinoid complexes based on Schiff-base ligands. Our work focuses on the significant advances that have occurred since 2000, with special attention on recent developments. The review is divided into eight sections (chapters). After an introductory section describing the organization of the scientific information, Sections 2 and 3 deal with general information about Schiff bases and their coordination chemistry, and the chemistry of actinoids, respectively. Section 4 highlights the relevance of Schiff bases to actinoid chemistry. Sections 5–7 are the “main menu” of the scientific meal of this review. The discussion is arranged according the actinoid (only for Np, Th and U are Schiff-base complexes known). Sections 5 and 7 are further arranged into parts according to the oxidation states of Np and U, respectively, because the coordination chemistry of these metals is very much dependent on their oxidation state. In Section 8, some concluding comments are presented and a brief prognosis for the future is attempted.
