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

Abstract 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 (π–π ∗ ) interactions lead to the unusual intense fluorescent emission upon photoexcitation.
