Macrocyclic control of electron transfer to high valent uranium in heterobimetallic complexes.

ABSTRACT: The redox properties of the uranyl ion, UO₂²⁺, influence the chemistry required for nuclear fuel reprocessing, but little spectroscopic insight is available to support design strategies for influencing the redox properties of uranium complexes. Here, structural studies with X-ray diffraction analysis, electrochemical methods, and Raman spectroscopy have been used to examine one strategy for influencing uranyl redox chemistry, namely co-encapsulation of UO₂²⁺ and secondary metal cations (Cs⁺, Rb⁺, K⁺, Na⁺, Li⁺, and Ca²⁺) in macrocyclic ligands. Two ligands are compared in this work that differ in the denticities of their secondary cation binding sites (pentadentate vs. hexade
