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.
