摘要：
A novel organic-inorganic hybrid hexa-Ni-II sandwiched germanotungstate [enH(2)](2)[Ni(en)(2)](2){[Ni-6(en)(2)(H2O)(2)] [B-alpha-GeW9O34](2))center dot 14H(2)O (1) has been hydrothermally synthesized and structurally characterized. 1 consists of a hexa-nickel sandwiched polyoxoanion {[Ni-6(en)(2)(H2O)(2)][B-alpha-GeW9O34](2)}(8-), two discrete [Ni(en)(2)](2+) cations, two free diprotonated [enH(2)](2+) cations and fourteen lattice water molecules. Notably, the sandwich-type polyoxoanion {[Ni-6(en)(2)(H2O)(2)][B-alpha-GeW9O34](2)}(8-) is constructed from two trivacant [B-alpha-GeW9O34](10-) Keggin moieties in a staggered fashion linked via a belt hexa-nickel cluster [Ni-6(en)(2)(H2O)(2)](12+). To our knowledge, 1 represents the first hexa-N-II substituted sandwich-type germanotungstate. 1 shows the occurrence of ferromagnetic interactions within nickel centers. The photocatalytic property of 1 has been investigated. (c) 2011 Elsevier B.V. All rights reserved.
