Structural characterization of the first hydroxo-bridged plutonium compound, (PuO2)(2)(IO3)(mu(2)-OH)(3)
The hydrothermal reaction of a Pu-239(IV) stock solution in the presence of iodic acid and 1 M KOH produces reddish-brown single crystals Of (PuO2)(2)(IO3)(OH)(3). The structure consists of two-dimensional layers forming in the ac plane and is the first single-crystal structure of plutonium(VI) connected through hydroxide anions. The additional linkage of plutonium centers is completed through iodate ligands.
