Synthesis and property of three novel organically templated layered cerium materials

Three novel organically templated layered cerium materials, [enH2]0.5[CeIVF3(HPO4)] (CeFPO), [enH2]0.5[CeIII(PO4)(HSO4)(H2O)] (CePSO), and [enH2]0.5[CeIII(SO4)2] (CeSO), have been synthesized by hydrothermal synthesis techniques and characterized by single-crystal and powder XRD, TG-DTA, IR, ICP, CHN, and magnetic susceptibility measurement. These compounds possess unique cerium-centered polyhedra CeO3F5, CeO8(H2O), and CeO9, and their layers are separated by the ethylenediaminium cations.
