Abstract

A hybrid uranium-iron cage nanocluster, [(UO₂)₂₄(FeOH)₂₄(O₂)₂₄(PO₄)₈(CH(COO)(PO₃)₂)₂₄]^96- (U₂₄Fe₂₄), was synthesized using bridging ligands containing bisphosphonate and carboxylate groups. U₂₄Fe₂₄ contains six tetramers of uranyl hexagonal bipyramids and eight iron trimers, each of which consists of three corner-sharing Fe³⁺ octahedra and is stabilized by in situ formed phosphate and 2,2-bis(phosphonato)acetate (C₂P₂) groups. Tetramers and trimers are bridged by 24 C₂P₂ groups into a cage cluster. Crystals of U₂₄Fe₂₄ present a paramagnetic-like behavior. X-ray scattering showed that U₂₄Fe₂₄ forms in the reactant solution prior to crystallization and is stable upon dissolution in water.
