    摘要:
    The present research describes the synthesis of the citrate of Pr by the amorphous citrate method and the study of the thermal decomposition of the complex in air, nitrogen and oxygen, in order to identify the final compounds and the intermediates obtained during the decomposition. A special study was dedicated to the thermal decomposition of the Pr-carbonate octahydrate used in the synthesis as starting material. The thermal decomposition of the lanthanide citrate was investigated mainly by thermogravimetry, differential thermal analysis, X-ray diffraction and infrared spectroscopy. The results showed that the complex decomposes to PrO1.83 with formation of an intermediate oxycarbonate compound in air or directly to the oxide in oxygen; in nitrogen atmosphere, amorphous products were obtained after thermal decomposition.

    摘要:
    在这项研究中,通过稀土氯化物或硝酸盐与预制 3-糠酸钠之间的复分解反应合成了两种类型的稀土 (RE) 3-糠酸盐配合物。两种不同的结构基序被确定为 1RE 型和 2RE 型。1RE 型单金属配合物形成二维聚合物网络,组成为 [RE(3fur)3(H2O)2]n(1RE = 1La、1Ce、1Pr、1Nd、1Gd、1Dy、1Ho、1Y;3furH = 3-糠酸)而 2RE 型双金属配合物形成 3D 聚合物系统 [NaRE(3fur)4]n (2RE = 2Ho, 2Y, 2Er, 2Yb, 2Lu)。复分解反应中使用的化学计量摩尔比(RE: Na(3fur) = 1:3 或 1:4)决定是形成 1RE 还是 2RE(RE = Ho 或 Y),但 2RE(RE = Er、Yb、Lu ) 的获得与比率无关。通过在 0.01 M NaCl 介质中对 AS1020 低碳钢表面进行浸没研究和电化学测量

  • Different hydrated forms of the ethylenediaminetetraacetato complexes of the light rare earths
    作者:J.Linn Mackey、David E. Goodney、James R. Cast

    日期:1971.11
    The reaction between the carbonates of the light rare earths and ethylenediaminetetraacetic acid (EDTA) yields different forms of the protonated 1:1 rare earth-EDTA chelates depending on the temperature. Near room temperature, multihydrates are formed (H[Ln(EDTA)]·nH2O, where n = 7 or 5), while above 45°C H[Ln(EDTA)]·mH2O is formed where m = 1 or 0. These chelates have been characterized by i.r., TGA
    轻稀土的碳酸盐与乙二胺四乙酸(EDTA)之间的反应会根据温度产生不同形式的质子化1:1稀土-EDTA螯合物。在室温附近,会形成多水合物(H [Ln(EDTA)]· n H 2 O,其中n = 7或5),而在45°CH以上,会形成多水合物CH [Ln(EDTA)]· m H 2 O,其中m = 1或0。这些螯合物的特征在于ir,TGA和X射线粉末衍射。La,Ce,Pr和Nd的多水合物螯合物H [Ln(EDTA)]·7H 2 O是同构的,而H [Sm(EDTA)]·5H 2 O和H [Eu(EDTA)]·5H 2O形成不同的同构系列。红外光谱和溶解度表明这两个系列的结构不同。根据稀土的配位数,讨论了各种质子化1:1螯合物的稳定性和结构。

    Several triglycine complexes of rare earth chlorides have been prepared which have composition RCl32H3N+CH2COO−. 3H2O, where R = Y, La, Ce. Pr, Nd, Sm and Dy. The i.r. spectra of these complexes have been interpreted in terms of zwitterion structure of glycine which is coordinated to rare earth cations through oxygens of carboxylic group. The i.r. data together with thermal behaviour of above complexes

    Although a few open-framework metal sulfates and selenites have been synthesized and characterized recently, it has not been possible to prepare the corresponding selenates, probably because of the instability of the +6 oxidation state of Se in alkaline media. We have been able to synthesize, for the first time, organically templated open-framework rare earth selenates with the general formula 0.5[
    尽管最近已经合成并表征了一些开放骨架金属硫酸盐和亚硒酸盐,但尚无法制备相应的硒酸盐,可能是因为硒在碱性介质中的 +6 氧化态不稳定。我们首次能够合成通式为 0.5[C2N2H10][Ln(H2O)2(SeO4)2] (I)(Ln = La、Nd 或 Pr)的有机模板化开放框架稀土硒酸盐) 和 0.5[C4N2H14][La(SeO4)2]·0.5H2O (II),在酸性介质中的水热条件下。晶体数据: I (Ln = La): 三斜晶系,空间群 = P , Mr = 491.91, a = 7.0105(8) A, b = 7.3772(9) A, c = 9.526(1) A, α = 82.014(2) ), β = 84.514(2), γ = 84.247(2)°, V = 483.76(1) A3, Z = 2; II: 三斜, 空间群 = P , Mr = 478.91, a =

    Characterization, thermal stability and thermal decomposition of light trivalent lanthanide mandelates Ln(C 6 H 5 CH(OH)CO 2 ) 3 · n H 2 O (Ln = La to Gd, except Pm) were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG–DTA), differential scanning calorimetry (DSC), experimental and theoretical infrared spectroscopy, elemental analysis, X-ray diffractometry
    使用同步热重法和差热分析法研究了轻质三价镧系元素扁桃酸 Ln(C 6 H 5 CH(OH)CO 2 ) 3 · n H 2 O(Ln = La 到 Gd,Pm 除外)的表征、热稳定性和热分解(TG-DTA)、差示扫描量热法 (DSC)、实验和理论红外光谱、元素分析、X 射线衍射、络合法和 TG-DSC 与 FTIR 耦合。镧、钐、铕和钆化合物的脱水在一个步骤中发生,而对于镨和钕化合物,它在两个连续的步骤中发生。无水化合物的热分解发生在三个、四个或五个连续步骤中,形成各自的氧化物 CeO 2 、Pr 6 O 11 和 Ln 2 O 3 (Ln = La,Nd 至 Gd)作为最终残留物。结果还提供了有关这些化合物热分解过程中产生的成分、热行为和气态产物的信息。理论和实验光谱数据表明配体与镧的可能配位模式。
