tris[2-amido(2-pyridyl)ethyl]amine ligand, L, with thorium(IV) and uranium(IV). Using a salt-metathesis strategy from the potassium salt of this ligand, K3L, new actinide complexes were isolated, namely the dimeric thorium complex [ThCl(L)]2 (1) and the monomeric uranium complex UI(THF)(L) (2); under different crystallisation conditions, the dimeric uranium complex is also isolated, [UI(L)]2 (2-dimer). With
我们报告了三脚架三[2-氨基(2-吡啶基)乙基]胺配体L与th(IV)和铀(IV)的配位化学。使用该配位体钾盐K 3 L的盐复分解策略,分离了新的act系元素络合物,即二聚th络合物[ThCl(L)] 2(1)和单体铀络合物UI(THF)(L) )(2); 在不同的结晶条件下,还会分离出二聚铀络合物[UI(L)] 2(2-dimer)。为了研究电子现象,例如两个act系元素离子之间的磁交换,我们合成了第一个由双阴离子2,5-双[2,6-(二异丙基)苯胺] -1,醌型桥接act系元素络合物的实例, 4-苯醌(Q Dipp)和2,5-双[2-(甲氧基)苯胺] -1,4-苯醌(Q OMe)配体。所得的络合物为[Th(L)] 2 Q Dipp(3),[Th(THF)(L)] 2 Q OMe(5)和[U(L)] 2 Q OMe(6)。目标[U(L)] 2 Q Dipp复合物(4)无法隔离。所有分离的
