Abstract

Dibenzoylmethanate replaces the bridging triflate ligands in uranium triflate polyoxo-clusters and cleaves the U₁₂O₂₀ core yielding the new [U₆O₄(OH)₄(η-dbm) ₁₂] dibenzoylmethanate (dbm^-) cluster which slowly dissociates into a monomeric complex. This reactivity demonstrates the importance of bridging ligands in stabilizing uranium polyoxo-clusters.
