Abstract
After more than 50 years, the synthesis and electronic structure of the first and only reported “U0 complex” [U(bipy)4] (1) has been reinvestigated. Additionally, its one‐electron reduced product [Na(THF)6][U(bipy)4] (2) has been newly discovered. High resolution crystallographic analyses combined with magnetic and computational data show that 1 and its derivative 2 are best described as highly reduced species containing mid‐to‐high‐valent uranium ligated by redox non‐innocent ligands.
