| pubmed-article:15071196 | pubmed:abstractText | The crystal structures of dimagnesium disodium decavanadate icosahydrate, Mg(2)Na(2)V(10)O(28).20H(2)O, (I), and trimagnesium decavanadate octacosahydrate, Mg(3)V(10)O(28).28H(2)O, (II), have been determined by single-crystal X-ray diffraction. They crystallize with monoclinic (C2/c) and triclinic (P-1) symmetry, respectively. All the Mg(2+) cations in (I) and (II) are octahedrally coordinated by six water molecules. The Na(+) cations in (I) are coordinated by three water molecules and three O atoms of the decavanadate anions, and link the latter into a three-dimensional network. The decavanadate anions in (II) are not linked to one another. | lld:pubmed |
