An -aryloxide-amidine ligand (), [ONNO] ligand, integrating phenoxide (PhO) and amidine ligands through methylene linkers, was employed in actinide chemistry. Upon reaction of the deprotonated ligand with ThCl(DME) in ether, the corresponding dimer complex was obtained. Upon treatment of with KCp* (Cp* = Cp(Me)) in tetrahydrofuran, the corresponding {[ONNO]ThCp*(LiCl)} () was obtained. In complex , the two ArO arms bonded from the same ligand to different Th centers. In contrast, both ArO arms coordinated to the same metal center in . Notably, when a mixture of and bipyridine was treated with one or two equiv of KC, the [ONNO]Th-bipyridyl•̅ radical dimer complex () and [ONNO]Th-bipyridyl dianionic dimer species () were obtained, respectively.
一种通过亚甲基连接基将酚盐（PhO）和脒配体整合在一起的 -芳氧基 -脒配体（），即[ONNO]配体，被用于锕系元素化学中。在醚中，去质子化的配体与ThCl（DME）反应，得到了相应的二聚体配合物 。在四氢呋喃中，用KCp*（Cp* = Cp（Me））处理 ，得到了相应的{[ONNO]ThCp*（LiCl）}（）。在配合物 中，来自同一配体的两个ArO臂与不同的Th中心相连。相比之下，在 中两个ArO臂都与同一个金属中心配位。值得注意的是，当用一当量或两当量的KC处理 和联吡啶的混合物时，分别得到了[ONNO]Th -联吡啶•̅自由基二聚体配合物（）和[ONNO]Th -联吡啶二阴离子二聚体物种（）。
