Structural characterization and luminescence behavior of a 2D silver (I) coordination polymer assembled from pyridine-2,6-dicarboxylic acid N-oxide

A 2D network complex [Ag-2(pydco)](n) (1) (pydco = pyridine-2,6-dicarboxylic acid N-oxide) was synthesized and structurally characterized. Fluorescence spectrum of complex 1 and the free ligand indicates that the cooperative association of Ag-Ag contacts and the intraligand (pi-pi*) interactions lead to the unusual intense fluorescent emission upon photoexcitation.
