چکیده
The bis(imido) uranium(VI)-C(5)H(5) and -C(5)Me(5) complexes (C(5)H(5))(2)U(N(t)Bu)(2), (C(5)Me(5))(2)U(N(t)Bu)(2), (C(5)H(5))U(N(t)Bu)(2)(I)(dmpe), and (C(5)H(5))(2)U(N(t)Bu)(2)(dmpe) can be synthesized from reactions between U(N(t)Bu)(2)(I)(2)(L)(x) (L=THF, x=2; L=dmpe, x=1) and Na(C(5)R(5)) (R=H, Me); these complexes represent the first structurally characterized C(5)H(5)-compounds of uranium(VI) and they further highlight the differences between UO(2)(2+) and the bis(imido) fragment.

Exploring the coordination modes of pyrrolyl ligands in bis(imido) uranium(VI) complexes.
The preparation of a family of bis(imido) uranium(VI) complexes stabilized by mono- and bidentate pyrrolyl ancillary ligands is described. X-ray crystallographic studies of dipyrrolylmethane (dpm) derivatives show that the pyrrolyl coordination mode in these uranium(VI) ions is unexpected in comparison to analogous transition metal and lanthanide chemistry. The ability of the coordinated pyrrol...
متن کاملSynthesis and reactivity of cyclopentadienyl chloro, imido and alkylidene tungsten (VI) complexes
This paper describes the synthesis and characterization of alkylidene pentamethylcyclopentadienyl imido tungsten(VI) complexes via a-hydrogen abstraction processes from suitable alkyl derivatives. Reaction of WCp*Cl4 with one equivalent of NH2R (R= Bu, 2,6-Me2–C6H3), two equivalents of NEt3 and subsequent oxidation with PCl5 affords the pentamethylcyclopentadienyl imido tungsten derivatives, WC...
متن کاملSynthesis, Characterization, and Reactivity of a Uranium(VI) Carbene Imido Oxo Complex**
We report the uranium(VI) carbene imido oxo complex [U(BIPM(TMS))(NMes)(O)(DMAP)2] (5, BIPM(TMS) = C(PPh2 NSiMe3)2; Mes = 2,4,6-Me3C6H2; DMAP = 4-(dimethylamino)pyridine) which exhibits the unprecedented arrangement of three formal multiply bonded ligands to one metal center where the coordinated heteroatoms derive from different element groups. This complex was prepared by incorporation of car...
متن کاملExchange of an imido ligand in bis(imido) complexes of uranium.
Addition of B(C6H5)3.H2O to U(NtBu)2I2(THF)2 provides U(NtBu)(O)I2(THF)2, a complex with a trans arrangement of the oxo and imido ligands. A DFT study on the Ph3PO adduct, U(NtBu)(O)I2(Ph3PO)2, reveals that there are six bonding orbitals in the O=U=N interaction, much like the bis(imido) N=U=N interaction. However, the calculations suggest that the multiple bonding in the oxo imido complexes is...
متن کاملCharge control of the inverse trans-influence.
The synthesis and characterization of uranium(VI) mono(imido) complexes, by the oxidation of corresponding uranium(V) species, are presented. These experimental results, paired with DFT analyses, allow for the comparison of the electronic structure of uranium(VI) mono(oxo) and mono(imido) ligands within a conserved ligand framework and demonstrate that the magnitude of the ground state stabiliz...
