Self-assembly of novel supramolecular silver(I) compound based on mixed ligands bipy/TST3- H3TST=2,4,6-tris (4-sulfophenylamino)-1,3,5-triazine

The novel supramolecular silver(I) compound with formula [Ag-6(TST)(2)(bipy)(6)(H2O)(2)](n) center dot 3nH(2)O (1) based on assembly of Ag(I) and mixed ligand bipy/TST3-, bipy = 2,2'-bipyridine, H3TST = 2,4,6-tris(4-sulfophenylamino)-1,3,5-triazine, has been prepared by hydrothermal method. In the solid-state structure of 1, two-dimensional layered polymeric structures extended with subunits [Ag-6(TST)(2)(bipy)(6)(H2O)(2)] interact each other in the form of pi-pi attractions between bipy, forming a three-dimensional supramolecular architecture. Compound 1 represents a Ag-containing polymeric compound possessing room-temperature luminescence. (c) 2007 Elsevier B.V. All rights reserved.
