Abstract In an effort to better understand the nature of the species which may be involved in the selective extraction of actinides over the lanthanides – relevant to nuclear reprocessing – by 2,2′:6′,2″-terpyridine (terpy)-type ligands, in synergistic combination with a liphophilic carboxylic acid coextractant, the Pr III / PhCO 2 - / NO 3 - / terpy reaction system has been investigated. The investigation
摘要 为了更好地了解可能涉及通过 2,2':6',2"-三联吡啶 (terpy) 型配体选择性提取锕系元素而不是镧系元素的物种的性质 - 与核后处理相关, 与亲脂性羧酸共萃取剂协同组合,研究了 Pr III / PhCO 2 - / NO 3 - / terpy 反应体系。研究结果分离出双核配合物 [Pr2(O2CPh)5(NO3)(terpy)2(H2O)(MeOH)] (1),其中金属离子由两个 η1:η1:μ2 苯甲酸盐配体桥接. 从反应混合物中省略硝酸盐得到结构相似的复合物 [Pr2(O2CPh)6(terpy)2(H2O)2] (2)。IR 和固态电子光谱根据键合的性质和已知结构进行了讨论。
