A Convenient Entry into Trivalent Actinide Chemistry: Synthesis and Characterization of AnI3(THF)4 and An[N(SiMe3)2]3 (An = U, Np, Pu)

A Heterobimetallic Complex With an Unsupported Uranium(III)−Aluminum(I) Bond: (CpSiMe3)3U−AlCp* (Cp* = C5Me5)

“…17 Finally, the room-temperature electronic absorption spectrum of 1 exhibits a series of Laporteforbidden f→f bands between 500 and 1500 nm which are typical of the electronic "fingerprint" observed for trivalent uranium compounds. 17,18 Further support for the absence of a bridging hydride in 1 was found in its reactivity toward CCl 4 . 19 A sample of 1 in C 6 D 12 was analyzed by 1 H NMR spectroscopy before and after addition of 1 and 10 molar equivalents of CCl 4 .…”

Organometallic neptunium(III) complexes

“…Hybrid density functional theory (DFT) calculations found significant covalent bonding in both binding modes in the di-U III adduct 16 . We have also used non-aqueous Np III iodides 17 to make magnetically coupled U III and Np III complexes that we could not structurally characterise 18 . We here 65 report our successful attempts to demonstrate that organometallic ligands other than the cyclopentadienyl anion, i.e.…”

Self‐Assembly of Polyoxo Clusters and Extended Frameworks by Controlled Hydrolysis of Low‐Valent Uranium

“…A series of mixed-valence uranium oxo clusters were structurally characterized, anticipating the fascinating structural variety of this chemistry. We found four remarkably different structures (Figure 1 The reaction of [UI 3 (thf) 4 ] [27] with two equivalents of H 2 O in the presence of potassium triflate at room temperature in acetonitrile results in a rapid color change of the solution from dark green to brown. After 15 h, the color of the O 20 core, as the final reaction product.…”
