Synthesis, Structure, and Luminescent Property of a 3D Polymer Containing Silver Ions

The hydrothermal reaction of Ag 2 SO 4 , pyridine-3,4-dicarboxylic acid (H 2 PDC), LiF, and H 2 O led to the formation of a novel complex, [Ag 2 (PDC)] n (1). X-ray crystal structural analysis indicates that 1 has a 3D coordinated framework, which contains a mono- and dinuclear mixed ID polymeric chain. Fluorescent analyses of 1 show intense photoluminescence at 510nm in the solid state, suggesting potential candidates for photoactive material.
