    Pentavalent and Tetravalent Uranium Selenides, Tl3Cu4USe6 and Tl2Ag2USe4: Syntheses, Characterization, and Structural Comparison to Other Layered Actinide Chalcogenide Compounds
    摘要:
    The compounds Tl3Cu4USe6 and Tl2Ag2USe4 were synthesized by the reaction of the elements in excess TlCl at 1123 K. Both compounds crystallize in new structure types, in space groups P2(1)/c and C2/m, respectively, of the monoclinic system. Each compound contains layers of USe6 octahedra and MSe4 (M = Cu, Ag) tetrahedra, separated by Tl+ cations. The packing of the octahedra and the tetrahedra within the layers is compared to the packing arrangements found in other layered actinide chalcogenides. Tl3Cu4USe6 displays peaks in its magnetic susceptibility at 5 and 70 K. It exhibits modified Curie Weiss paramagnetic behavior with in effective magnetic moment of 1.58(1) mu(B) in the temperature range 72-300 K, whereas Tl2Ag2USe4 exhibits modified Curie-Weiss Paramagnetic behavior with mu(eff) = 3.4(1) mu(B) in the temperature 100-300 K. X-ray absorption near-edge structure (XANES) results from scanning transmission X-ray spectromicroscopy confirm that Tl2Cu4USe6 has Se bonding characteristic of discrete Se2- units, Cu bonding generally representative of Cu+, and U bonding consistent with a U4+ or U5+ species. On the basis of these measurements, as well as bonding arguments, the formal oxidation states for U may be assigned as +5 in Tl3Cu4USe6 and +4 in Tl2Ag2USe4.

    UT 合金中的氢:UH3-V 的晶体结构和磁性
    摘要:
    摘要 采用超快冷却制备了具有可变相组成的 UV 合金。15 at.% V 不足以完全抑制正交 α-U 型相,更高的合金浓度会导致纯钒的偏析。该合金在 105 Pa 的压力下相对于 H2 暴露是稳定的。然而,在高 H2 压力下氢化进行缓慢。生成的氢化物具有常见的 β-UH3 结构。这在 UT 系统中是不寻常的,它产生 α-UH3 或纳米晶 β-UH3 结构。UH3-V 系统是铁磁性的,居里温度随着 V 浓度单调增加到 TC = 190 K,对于 15 at.% V。磁矩保持在 1.0 μB/U 的水平。结果证明 UH3-T 型合金化 U 氢化物中 TC 的增加不依赖于特定的结构细节或 T 元素的类型,尽管后者在一定程度上改变了所达到的最大 TC 值。假设 U 被 T 取代提供了增强的 H/U 比,可以理解这种情况,而 UH 相互作用是 5f 矩形成和排序的重要元素。

    complexes with different coordination environments. Two practical synthetic methods for the preparation of Lewis base adducts of U(OTf)3 are described. Analytically pure [U(OTf)3(py)4] (4) was easily and reproducibly prepared (50-60% yield) by protonolysis of the amide UN(SiMe3)2}3 with pyridinium triflate in pyridine. Salt metathesis of UI3(thf)4 with potassium triflate in acetonitrile resulted in the

    Enthalpies of solution of UF 3 and UF 4 in a mixed aqueous solvent containing sulphuric acid, boric acid, and ceric sulphate have been measured calorimetrically. Together with measurements of the enthalpy of solution of γ-UO 3 and U 3 O 8 in the same solution, the standard enthalpies of formation of solid UF 3 and UF 4 have been derived: Δ H f o ( UF 3 , s , 298.15 K ) = − ( 1508.5 ± 5.5 ) kJ mol −

    Abstract Enthalpies of solution of UCl 3 in H 2 SO 4 (aq) have been measured calorimetrically. In the same way enthalpies of solution of UCl 5 and UCl 6 have been measured in (HCl + FeCl 3 )(aq) and HCl(aq), respectively. Together with data for the auxiliary reactions, the standard enthalpies of formation of UCl 3 (s), UCl 5 (s), and UCl 6 (s) have been derived. The results obtained are as follows:

  • Reactivity of UH3 with mild oxidants
    作者:David D. Schnaars、Guang Wu、Trevor W. Hayton
    DOI:10.1039/b809184f
    日期:——
    Addition of 2 equiv of I2 to a stirring suspension of UH3 in Et2O results in vigorous gas evolution and the formation of UI4(OEt2)2 (1), which can be isolated in good yields as an air- and moisture-sensitive brick-red powder. Addition of 3 equiv of AgBr to UH3 in DME produces UBr3(DME)2 (2), while addition of 4 equiv of AgX to UH3 in DME–CH2Cl2 provides UX4(DME)2 (X = Br, 3; Cl, 4). Similarly, the reaction of 4 equiv of AgOTf with UH3 in neat DME generates U(OTf)4(DME)2 (5). Each of these reactions proceeds with the evolution of hydrogen. Complex 1 can also be generated by reaction of 4 equiv of Me3SiI with UCl4 in Et2O. All complexes were fully characterized, including analysis by X-ray crystallography.
    向 UH3 在 Et2O 中的搅拌悬浮液中加入 2 等量的 I2 会产生剧烈的气体演化,并形成 UI4(OEt2)2 (1),这种对空气和湿气敏感的砖红色粉末可以很好地分离出来。在二甲醚中向 UH3 加入 3 等量的 AgBr 会生成 UBr3(DME)2 (2),而在二甲醚-CH2Cl2 中向 UH3 加入 4 等量的 AgX 会生成 UX4(DME)2(X = Br,3;Cl,4)。同样,在纯二甲醚中,4 等量的 AgOTf 与 UH3 反应生成 U(OTf)4(DME)2 (5)。上述每个反应都伴随着氢的进化。络合物 1 也可以通过 4 等量的 Me3SiI 与 UCl4 在 Et2O 中的反应生成。所有络合物都经过了全面的表征,包括 X 射线晶体学分析。

    Abstract The results of a neutron powder diffraction study on β-UD 3 and β-UH 3 are reported. Diffraction patterns have been obtained both above (220 K) and below (10 K) the Curie temperature, in order to refine the crystal structure on the basis of a large number of resolved Bragg peaks and to obtain the ordered magnetic moment. The two kinds of uranium atoms present in the structure appear to be
