摘要
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.
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, /3 = 97.332（7）°, V=1. 115 5（7） nm^3, 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.
