The discovery that imido analogs of actinyl dioxo cations can be extended beyond uranium into the transuranic elements is presented. Synthesis of the Np(V) complex, Np(NDipp)2((t)Bu2bipy)2Cl (1), is achieved through treatment of a Np(IV) precursor with a bipyridine coligand and lithium-amide reagent. Complex 1 has been structurally characterized, analyzed by (1)H NMR and UV-vis-NIR spectroscopies, and the electronic structure evaluated by DFT calculations.
介绍了酰亚氨基类似物的钍酰二氧阳离子可以从铀延伸到超铀元素的发现。通过用联吡啶配体和锂酰胺试剂处理 Np(IV)前体，合成了 Np(V)配合物 Np(NDipp)2((t)Bu2bipy)2Cl（1）。通过 X 射线单晶衍射、（1）H NMR 和 UV-vis-NIR 光谱对配合物 1 进行了结构表征和分析，并通过 DFT 计算评估了其电子结构。
