摘要：

The first organically templated layered structure of scandium sulfate, (H(2)cn)Sc-2(SO4)(4)center dot(H2O)(0.72). (en = ethylenediamine) was synthesized by hydrothermal method and characterized by single crystal X-ray diffraction. In the title compound, scandium ions are bridged by sulfate groups with a ratio of 1:2 into a 4(3)(6) layer, structure. These layers are parallel packed and separated from each other by ethylenediammonium dictations and water molecules. The title compound crystallizes in the monoclinic space group P2/c. With cell parameters a = 8.5966(13) angstrom, b = 5.1068(8) angstrom, c = 18. 847(3) angstrom, beta = 91.210(3)degrees, V = 827.2(2) angstrom(3) and Z = 2. Refinement gave R-1[I > 2 sigma(I)] = 0.0354 and wR(2)[I > 2 sigma(I)] = 0.0878. Thermogravimetric analysis indicates that this material is thermally stable to above 400 degrees C.
