A Photoluminescent Polymeric 2D Silver(I) Complex Exhibits a Fishbone-Like 1D Silver Cluster and New Coordination Mode of the Pyridine-2,3

Abstract

In this study, a novel organic-inorganic hybrid compound with AgNO<inf>3</inf> and 2,3-pyridinedicarboxylic acid (H<inf>2</inf>pydc), [Ag<inf>2</inf>(μ<inf>6</inf>-pydc)]<inf>n</inf>(1) has been synthesized. The molecular structure of complex has been determined by the single crystal X-ray diffraction. The complex has been observed to crystallize in the monoclinic space group P2<inf>1</inf>/c. The asymmetric unit of compound consists of two crystallographically different Ag(I) centers and one pydc ligand. The Ag1 and Ag2 adopt tetrahedral and T-shaped geometries, respectively. At the same time, the silver(I) compound consists of a fish bone similar to the 1D silver cluster. Furthermore, novel coordination mode shown by H<inf>2</inf>pydc indicates that the crystal exhibits photoluminescence in the solid state at room temperature. © 2012 Springer Science+Business Media New York.
