Abstract

Two oxo-containing neptunium(IV) -butoxides, [NpO(OBu)] () and [KNpO(OBu)] (), were synthesized using the ligand substitution between neptunium(IV) silylamides and HOBu, whereas the salt metathesis between [NpCl(DME)] (DME = dimethoxyethane) and various amounts of LiOBu resulted in the formation of oxo-free alkoxides [Np(OBu)(py)] (; py = pyridine) and [Li(THF)][Np(OBu)] (; THF = tetrahydrofuran). These complexes are the first structurally characterized neptunium(IV) alkoxides using single-crystal X-ray diffraction and solid-state absorption spectroscopy, which provide data for the development of anhydrous metal-organic neptunium chemistry.

摘要

两种含氧的四价镎(IV)-丁氧基化合物，NpO(OBu)和KNpO(OBu)，是通过镎(IV)硅酰胺与 HOBu 之间的配体取代反应合成的，而 [NpCl(DME)]（DME = 二甲氧基乙烷）与不同量的 LiOBu 之间的盐复分解反应则生成了无氧的烷氧基化合物[Np(OBu)(py)]（; py = 吡啶）和 [Li(THF)][Np(OBu)]（; THF = 四氢呋喃）。这些配合物是首次通过单晶 X 射线衍射和固态吸收光谱学对四价镎(IV)烷氧基化合物进行结构表征的，为无水金属有机镎化学的发展提供了数据。
