    摘要:
    研究了NpO2+和UO22+之间的阳离子-阳离子相互作用,采用分光光度法和微量热法在不同温度(283.15 K至358.15 K)和不同离子强度(3–4.5 mol dm⁻³)下进行。NpO2+和UO22+之间的阳离子-阳离子复合物较弱,但随着温度从283.15 K升高到358.15 K,其强度逐渐增强。通过微量热法首次直接测定了复合反应的摩尔焓为(4.2 ± 1.6)kJ mol⁻¹ (在298.15 K下),这与不同温度下的稳定常数趋势一致。复合反应的低而正的焓变和熵变支持了NpO2+与UO22+之间的阳离子-阳离子复合物属于内球类型。每个温度下,发现阳离子-阳离子复合物的稳定常数随着离子强度的增加而增大。使用特定离子相互作用理论(SIT)获得了无限稀释和可变温度下的稳定常数。

    Crystalline compounds of the general composition Co(NH3)6PuO2(C2O4)2·nH2O (n = 2, 3, 5) were isolated from freshly prepared neutral oxalate solutions of Pu(V) by addition of Co(NH3)6 3+ ions. These compounds are fairly stable in storage in air and poorly soluble in water. Previously unknown double Np(V) oxalates Co(NH3)6NpO2(C2O4)·nH2O (n = 2, 5) were also synthesized and studied. All the compounds of Pu(V) and Np(V) of the same composition are mutually isostructural. The behavior of these compounds at heating was studied, and their IR spectra were measured. The optical spectra of new Np(V) compounds were measured.

  • New Neptunium(V) Borates That Exhibit the Alexandrite Effect
    作者:Shuao Wang、Evgeny V. Alekseev、Wulf Depmeier、Thomas E. Albrecht-Schmitt
    DOI:10.1021/ic201682s
    日期:2012.1.2
    A new neptunium(V) borate, K[(NpO2)B10O14(OH)4], was synthesized using boric acid as a reactive flux. The compound possesses a layered structure in which NpV resides in triangular holes, creating a hexagonal-bipyramidal environment around neptunium. This compound is unusual in that it exhibits the Alexandrite effect, a property that is typically restricted to neptunium(IV) compounds.
