The
hydrothermal reaction of PuCl3 or CeCl3 with
TeO2 in the presence of sulfuric acid under the
comparable conditions results in the crystallization of Pu(TeO3)(SO4) or Ce2(Te2O5)(SO4)2, respectively. Pu(TeO3)(SO4) and its isotypic compound Th(TeO3)(SO4) are characterized by a neutral layer structure with no interlamellar
charge-balancing ions. However, Ce2(Te2O5)(SO4)2 possesses a completely different
dense three-dimensional framework. Bond valence calculation and UV–vis–NIR
spectra indicate that the Ce compound is trivalent whereas the Pu
and Th compounds are tetravalent leading to the formation of significantly
different compounds. Pu(TeO3)(SO4), Th(TeO3)(SO4), and Ce2(Te2O5)(SO4)2 represent the first plutonium/thorium/cerium
tellurite sulfate compounds. Our study strongly suggests that the
chemistries of Pu and Ce are not the same, and this is another example
of the failure of Ce as a surrogate.
