A Novel Open-Framework Cerium Sulfate Hydrate: Synthesis and Characterization. — The new compound (H3O)0.5[Ce(SO4)1.5 (HSO4)0.5] is hydrothermally synthesized from an aq. solution of Ce(SO4)2, (NH4)2SO4, H3PO4, H2SO4, and H2N(CH2)2OH
(autoclave, 110 °C, 4—7 d). The new CeIII compound crystallizes in the monoclinic
space group Pm with Z = 2 (single crystal XRD). The structure contains CeO7 polyhedra and SO4 tetrahedra sharing corners in a strictly alternate manner to form a
three-dimensional framework with a one-dimensional eight-membered ring channel
system. Protonated water molecules are accommodated in these channels. — (YU, R.;
