Abstract

Two aqueous Pu^IV-desferrioxamine B (DFOB) complexes were characterized by one- and two-dimensional NMR techniques and an unexpected dimeric Pu^IVDFOB-di-μ-(O/OH)-Pu^IVDFOB 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. Two aqueous Pu^IV-desferrioxamine B (DFOB) complexes were characterized by 1D and 2D NMR techniques and a dimeric Pu^IVDFOB-di-μ-(O/OH)-Pu ^IVDFOB complex was identified. Both "Curie" and "anti-Curie" behavior were observed for the dimeric species, yet the monomer only showed "anti-Curie". Bond lengths and coordination numbers estimated from X-ray spectroscopic analysis support the proposed structures.
