Ligand assisted cleavage of uranium oxo-clusters.

Dibenzoylmethanate replaces the bridging triflate ligands in uranium triflate polyoxo-clusters and cleaves the U(12)O(20) core yielding the new [U(6)O(4)(OH)(4)(eta-dbm)(12)] dibenzoylmethanate (dbm(-)) cluster which slowly dissociates into a monomeric complex. This reactivity demonstrates the importance of bridging ligands in stabilizing uranium polyoxo… CONTINUE READING
