Two aqueous Pu IV ‐desferrioxamine B (DFOB) complexes were characterized by one‐ and two‐dimensional NMR techniques and an unexpected dimeric Pu IV DFOB‐di‐μ‐(O/OH)‐Pu IV DFOB complex was identified. Both “Curie” and “anti‐Curie” behavior were observed for the dimeric species, yet the monomeric species only showed “anti‐Curie” behavior. Diffusion ordered spectroscopy experiments showed an increase in particle size for the two species, which is indicative of a dimeric species. Bond lengths and coordination numbers estimated from X‐ray absorption spectroscopy are consistent with the proposed structures.
