Title: Hydrothermal synthesis and crystal structure of a new inorganic/organic hybrid of scandium sulfate: (H{sub 2}en)Sc{sub 2}(SO{sub 4}){sub 4}.(H{sub 2}O){sub 0.72}

Abstract

The first organically templated layered structure of scandium sulfate, (H{sub 2}en)Sc{sub 2}(SO{sub 4}){sub 4}.(H{sub 2}O){sub 0.72}, (en=ethylenediamine) was synthesized by a 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{sub 3}{sup 6} layer structure. These layers are parallel packed and separated from each other by ethylenediammonium dications and water molecules. The title compound crystallizes in the monoclinic space group P2/c, with cell parameters a=8.5966(13)A, b=5.1068(8)A, c=18.847(3)A, {beta}=91.210(3){sup o}, V=827.2(2)A{sup 3} and Z=2. Refinement gave R{sub 1}[I>2{sigma}(I)]=0.0354 and wR{sub 2}[I>2{sigma}(I)]=0.0878. Thermogravimetric analysis indicates that this material is thermally stable to above 400 deg. C.
