“…Cp*E are believed to be good s-donors. 243 According to the natural bond orbital/natural localized molecular orbital (NBO/NLMO) analysis, the bond U-E consists predominantly of an E -U s-interaction arising from favorable overlap between the diffuse ligand lone pair and the primarily 7s/6d acceptor orbitals on U(III), with negligible U -E p-donation. In another complex [(tren-SiMe 3 )(THF)U-Ga(NArCH) 2 ] (tren-SiMe 3 = N(CH 2 CH 2 -NSiMe 3 ), Ar = 2,6-i Pr 2 C 6 H 3 ), 244 the DFT calculations suggest a strongly electrostatic U-Ga bond with p-donation from the Ga-heterocycle to an empty 5f z2y orbital of U.…”

Recent advances in computational actinoid chemistry

We briefly review advances in computational actinoid (An) chemistry during the past ten years in regard to two issues: the geometrical and electronic structures, and reactions. The former addresses the An-O, An-C, and M-An (M is a metal atom including An) bonds in the actinoid molecular systems, including actinoid oxo and oxide species, actinoid-carbenoid, dinuclear and diatomic systems, and the latter the hydration and ligand exchange, the disproportionation, the oxidation, the reduction of uranyl, hydroamination, and the photolysis of uranium azide. Concerning their relevance to the electronic structures and reactions of actinoids and their importance in the development of an advanced nuclear fuel cycle, we also mentioned the work on actinoid carbides and nitrides, which have been proposed to be candidates of the next generation of nuclear fuel, and the oxidation of PuO(x), which is important to understand the speciation of actinoids in the environment, followed by a brief discussion on the urgent need for a heavier involvement of computational actinoid chemistry in developing advanced reprocessing protocols of spent nuclear fuel. The paper is concluded with an outlook.

“…Such species are of interest not only from a fundamental structure/bonding perspective [20,21], but also from the viewpoint of potential applications of this class of compounds (e.g. in the chemical synthesis of intermetallic nanomaterials) [22][23][24]. We have shown that low coordination Ga(I) species containing bulky aryl ligands Ar 0 GaGaAr 0 (Ar 0 = C 6 H 3 -2,6-(Dipp) 2 ) or GaL (L = HC[C(Me)N(Dipp)] 2 , Dipp = 2,6-iPr 2 C 6 H 3 ) are monomeric in solution and exhibit Lewis base behavior toward iron carbonyl to give monomeric Ar 0 GaFe(CO) 4 or LGaFe(CO) 4 complexes [25][26][27].…”

Reaction of Ni(CO) 4 in toluene at room temperature with one equivalent of GaAr 0 (Ar 0 = C 6 H 3 -2,6-(C 6 H 3 -2,6-iPr 2 ) 2 ) and GaL (L = HC[C(Me)N(C 6 H 3 -2,6-iPr 2 )] 2 ) formed the mono-substituted Ni(CO) 3 (GaAr 0 ) (1) and Ni(CO) 3 (GaL) (3), respectively. Compound 1 decomposed under reduced pressure or upon heating in toluene to give the new cluster species Ni 4 (CO) 7 (GaAr 0 ) 3 (2). Reaction of 3 with a second equivalent of GaL in toluene at 95°C afforded the disubstituted complex Ni(CO) 2 (GaL) 2 (4). All the compounds were characterized by IR, 1 H and 13 C{ 1 H} NMR spectroscopy and X-ray crystallographic studies were undertaken to elucidate the structures of the complexes 2, 3 and 4.
