Unusual coordination for plutonium(IV), cerium(IV), and zirconium(IV) in the cationic layered materials [M2Te4O11]X2 (M = Pu, Ce, Zr; X = Cl, Br).
Four isotypic cationic layered materials, [Pu(2)Te(4)O(11)]Cl(2), [Ce(2)Te(4)O(11)]Cl(2), [Zr(2)Te(4)O(11)]Cl(2), and [Zr(2)Te(4)O(11)]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.
