Abstract: An acidic cerium sulfate hydrate,H3O[Ce(SO4)2(H2O)3] H2O,was hydrothermally synthesized and characterized by single crystal X-ray diffraction.The compound crystallizes in monoclinic system,space group P21/c with cell parameters: a=0.677 8(3) nm,b=1.908 2(7) nm,c=0.882 7(3) nm,β=97.332(7)°,V=1.115 5(7) nm3,Z=4,R1=0.029 5,wR2=0.065 0,GOF=0.974.It possesses a layered anion framework constructed of CeO9 tetradecahedra and SO4 tetrahedra with H3O+ ion and H2O molecules located in the aperture of the inorganic layers to balance the negative charge of the framework and stabilized the three-dimensional structure by hydrogen bonding within and between the neighboring layers.The thermal analysis of the compound was also carried out.

Key words: Cerium sulfate hydrate, Hydrothermal synthesis, Structure characterization
