摘要：

Two new supramolecular assemblies based on Keggin-type polyoxometalates, [Ag-3(4,4'-bipy)(2)-(2.2'-bipy)(2)][{Ag(2,2'-bipy)}HSiW11VO40] (1) and [Ag-3(4,4'-bipy)(2)(2,2'-bipy)(2)][Ag(2,2'-bipy)(2)]- [{Ag(2,2'-bipy)}PW11VO40 (2) (4,4'-bipy = 4,4'-bipyridine, 2,2'-bipy = 2,2'-bipyridine), have been synthesized under the hydrothermal conditions and structurally characterized by IR, XPS, TG and single-crystal X-ray diffraction. Compound 1 has a 2D layer network structure via weak Ag center dot center dot center dot O interactions. Compound 2 is isostructural with compound 1. In addition, the fluorescence of compound 1 is reported. (c) 2008 Elsevier B.V. All rights reserved.
