A Look at the Chemistry of Einsteinium and other Trans-Plutonium Elements

May 7, 2022 | | 6 min read

Despite all of this the team at Berkeley was still able to learn a significant amount about the largely unexplored chemistry of einsteinium. While X-ray crystallography was considered, ultimately it was decided to explore the chemistry of einsteinium in relation to the ligand 3,4,3-LI(1,2-HOPO) which is pictured below in Figure 1.
