Unusual Coordination for Plutonium(IV), Cerium(IV), and Zirconium(IV) in the Cationic Layered Materials [M2Te4O11]X-2 (M = Pu, Ce, Zr; X = Cl, Br)
Four isotypic cationic layered materials, [Pu2Te4O11]Cl-2, [Ce2Te4O11]Cl-2, [Zr2Te4O11]Cl-2, and [Zr2Te4O11]Br-2, have been prepared under hydrothermal conditions. Single crystal diffraction studies reveal that these materials possess cationic Pu/Ce/Zr tellurite layers with halides as interlamellar charge-balancing anions. The Pu-IV, Ce-IV, and Zr-IV centers of the cationic layers exhibit a quite rare pentagonal bipyramid coordination environment.
