  摘要二价钴，镍和铜与配体N，N，N'，N'-四甲基吡啶-2,6-二甲酰胺（tdpa），N，N'-二甲基-N，N'-二苯基吡啶-2，为了说明这些配体的性质，讨论了6-二甲酰胺（dpda）和N，N，N'，N'-四异丙基吡啶-2,6-二甲酰胺（ppda）。配合物[M-（ppda）2（ClO4）2（M = Co，Ni和Cu）和[Co-（ppda）2]（ClO4）2（acet）（acet =丙酮）扭曲了八面体发色团。变形在[Cu（ppda）2]（ClO4）2中最明显。在八面体[Ni（tdpa）2]-（CIO4）2中不存在这种严重变形。从热溶液中分离出同构的晶体（MCl2）3（tdpa）12（M = Ni和Co）。固体反射光谱解析为高斯分量。这些数据，结合红外和磁测量，允许将式[MC1（tpda）] 2 [MCl4]分配给这些配合物。发现该阴离子为四面体，而阳离子具有扭曲的四面体发色团。NiBr2与d

  A method for separating and recovering trivalent and tetravalent actinoids in a simple and less costly manner without using an organophosphorus compound is provided. This method selectively separates and recovers the tetravalent actinoid plutonium Pu (IV) and the trivalent actinoids americium Am (III) and curium Cm (III) from trivalent lanthanoids Ln (III), etc. with the use of an extractant having a functional group with neutral multidentate ligand activity which is a hybrid donor type organic compound having both of donor atoms, i.e., an oxygen atom and a nitrogen atom.

  本发明提供了一种不使用有机磷化合物，以简单、低成本的方式分离和回收三价和四价锕系元素的方法。该方法利用一种具有中性多叉配体活性官能团的萃取剂，从三价镧系元素 Ln (III) 等中选择性地分离和回收四价锕系元素钚 (IV)、三价锕系元素镅 (Am (III) 和锔 (Cm(III))，该萃取剂是一种混合供体型有机化合物，具有两个供体原子，即一个氧原子和一个氮原子。

  The tridentate ligand N,N'-dimethyl-N,N'-diphenylpyridine-2,6-dicarboxyamide (DMDPhPDA) and the corresponding lanthanum complex [La(NO3)(3)(DMDPhPDA)(2)] have been prepared and structurally characterised. The crystal structure of DMDPhPDA shows syn-anti conformation. In the lanthanum complex, two DMDPhPDA molecules coordinated to La(III) in a tridentate fashion and to three nitrate ions in a bidentate fashion make the lanthanum atom 12-coordinate. The crystal structure of [La(NO3)(3)(DMDPhPDA)(2)] has a C-2 symmetry. The stability constants determined by spectrophotometric titration suggest that [Ln(DMDPhPDA)(2)](3+) is the primary product in CH3CN solution and [Ln(DMDPhPDA)(3)](3+) is difficult to form. However, [Ln(QMDPhPDA)(2)](3+) could not be distinguished in H-1 NMR spectra. The H-1 NMR titration results imply that a fast ligand exchange process takes place. (c) 2007 Elsevier B.V.
