Two novel sandwiched-type polyoxotungstates containing Zn6 transition-metal cluster: Syntheses, structures and luminescent property

Two novel Zn6 sandwiched polyoxometalates, [Zn(phen)2]2[Zn6(phen)2(AsW9O33)2] (1) and K11H2Zn [(ZnCl)6(AsW9O33)2]Cl · 27H2O (2), have been synthesized. Both of the polyoxoanions can be viewed as two [AsIIIW9O33]9− moieties linked by Zn6 transition-metal cluster.
