title: Plutonium(IV) cluster with a hexanuclear [Pu6(OH)4O4]12+ core.
abstract: A mixed hydroxo/oxo plutonium(IV) carboxylate resulting from the hydrolysis and condensation of Pu(IV) in an acidic aqueous solution has been isolated. The structure of Li6[Pu6(OH)4O4(H2O)6(HGly)12]Cl18·10.5H2O (1) consists of a cationic [Pu6(OH)4O4](12+) core that is decorated by glycine ligands. The synthesis, structure, and characterization of the hexanuclear unit, which represents the first example of a Pu(IV) polynuclear complex containing both hydroxo- and oxo-bridging ligands, are described herein.
