The reaction among amethyrin and non-aqueous uranyl silylamide (UO2[N(SiMe3)2]2) under anaerobic conditions afford a bench-stable uranyl complex. UV-Vis spectroscopy, cyclic voltammetry, as well as proton NMR spectroscopic analyses offer support for the conclusion that all six pyrrole subunits participate in coordination of the uranyl dication and that, upon complexation, the amethyrin-core undergoes a 2-electron oxidation to yield a formal 22 π-electron aromatic species.
