Caging Peroxide: Anion-Templated Synthesis and Characterization of a Rare-Earth Cluster

Sequestration of peroxide derived from molecular oxygen has resulted in the templated synthesis of a terbium picolinate cluster, isolated as a 2D sodiated network in the solid state. This first example of an air-stable rare-earth peroxide cluster represents key evidence for a peroxide-containing intermediate in rare-earth-cluster-catalyzed oxidation reactions. Luminescent and magnetic properties have also been investigated.
