Descripción
Sumario:The title compound, (C(10)H(10)N(2))(2)[SiW(12)O(40)]·C(10)H(8)N(2)·6H(2)O or (4,4′-bipyH(2))(2)[SiW(12)O(40)].(4,4′-bipy)·6H(2)O (4,4′-bipy is 4,4′-bipyridine), was prepared under hydro­thermal conditions. The asymmetric unit contains a discrete Keggin-type [SiW(12)O(40)](4−) anion (located on a twofold axis), one 4,4′-bipy (located on a twofold axis), two (4,4′-bipyH(2))(2+) cations and six uncoordinated water mol­ecules. The polyoxoanion is constructed from a central SiO(4) tetra­hedron which shares its O atoms with four trinuclear W(3)O(13) groups, each of which is made up of three edge-sharing WO(6) octa­hedra. The water mol­ecules and [SiW(12)O(40)](4−) anions are linked through hydrogen bonds.
