- 論文の詳細を見る
α-Ba<SUB>2</SUB>SiW<SUB>12</SUB>O<SUB>40</SUB>·16H<SUB>2</SUB>O is monoclinic, space group C2/c, with <I>a</I>=25.09(5), <I>b</I>=12.10(2), <I>c</I>=18.79(3) Å, β=122.5(3)°; <I>D</I><SUB>m</SUB>=4.95 g cm<SUP>−3</SUP> and <I>D</I><SUB>x</SUB>=4.78 g cm−3 for <I>Z</I>=4. The crystal consists of the well known Keggin ion SiW<SUB>12</SUB>O<SUB>40</SUB><SUP>4−</SUP>, having a SiO<SUB>4</SUB> tetrahedron in the center, bound by Ba<SUP>2+</SUP> and water molecules to form a three-dimensional framework. Four water molecules could not be located on electron-density maps, which seem to be disordered or <I>"zeolitic"</I>. The structural relationship of the Keggin ion to its isomer, the β-SiW<SUB>12</SUB>O<SUB>40</SUB><SUP>4−</SUP> polyanion found in β-K<SUB>4</SUB>SiW<SUB>12</SUB>O<SUB>40</SUB>·9H<SUB>2</SUB>O, is discussed. Mutual transformation between α- and β-isomers can occur through rotation of a W<SUB>3</SUB>O<SUB>13</SUB> group which is a building-unit of both α- and β-polyanions.
