    Synthesis of substitutional solid solutions in Na2O-P2O5-In2O3-M 2 III O3 (MIII = Cr, Fe, and Mn) systems
    摘要:
    Solid solutions based on Na-7(InP2O7)(4)PO4 and Na3In2(PO4)(3), where chromium, iron, and manganese substitute for indium, have been prepared. When chromium and iron substitute for indium in Na-7(InP2O7)(4)PO4, a continuous solid solution series exists. When manganese substitutes for indium, it enters the compound in the oxidation state +3. The substitution of chromium for indium in Na3In2(PO4)(3) occurs within the range from 0.11 to 0.74 (mol/mol), and that of iron for indium, from 0.09 to 0.62 (mol/mol). When manganese substitutes for indium, it enters the structure of the crystalline phase in insignificant amounts as a two-charged cation.

    A novel NBD-phenoxo-bridged dinuclear Zn(II) complex is found to be an effective colorimetric sensor for pyrophosphate (PPi) in pure aqueous solution over a wide pH range. This sensor shows high binding affinity (Ka ≈ 3 × 108 M−1) and high selectivity for PPi, and can be also used to assay the activity of pyrophosphatase in real time.

Here the bent configurations of four- and five-membered rings of uranyl peroxide hexagonal bipyramids are bridged by pyrophosphate or methylenediphosphonate, creating eight chemically complex cage clusters with specific topologies
    尽管在先进核能系统中具有潜在应用,但铀材料的纳米级控制仍处于起步阶段。在其六价状态下,U 以 (UO(2))(2+) 铀酰离子的形式出现,由各种配体协调以提供方形、五边形或六边形双锥。纳米结构铀酰材料的创造和设计需要中断铀酰双锥体共享赤道边缘以形成扩展结构中出现的无限片的趋势。在双齿过氧化物基团桥接铀酰双锥体的情况下,该构型固有地弯曲,促进了笼簇的形成。在这里,过氧化铀酰六方双锥体的四元环和五元环的弯曲构型由焦磷酸盐或亚甲基二膦酸盐桥接,形成了八个具有特定拓扑结构的化学复杂笼状簇。此类簇中的化学复杂性为调节笼尺寸、孔径和水溶性等性质提供了机会。其中一些是仅包含铀酰双锥的更简单簇的拓扑衍生物,而其他则表现出新的拓扑。
