A novel silver(І) coordination polymer based on mixed ligands bpp and 2,2′-bipyridine-4,4′-dicarboxylate

A novel coordination polymer based on silver(І) and mixed ligands {[Ag2(bpdc)(bpp)(H2O)] · 2H2O}n (1) (H2bpdc = 2,2′-bipyridyl-4,4′-dicarboxylic acid, bpp = 1,3-bis(4-pyridyl)propane), has been prepared by hydrothermal method. Compound 1 has a 2D polymeric structure extended with subunits tetranuclear silver with Schläfli symbol {3^12;4^9;5^6;6^9}{3^18;4^22;5^5}. Compound 1 represents an Ag-containing polymeric compound possessing room-temperature luminescence.

Graphical abstractA novel coordination polymer based on silver(І) and mixed ligands [Ag2(bpdc)(bpp) · H2O]n · 2H2O (1), has been prepared by hydrothermal method. Compound 1 is the 2D polymeric structure extended with subunits tetranuclear silver, which are linked by ligand-unsupported Ag–Ag contacts. The compound 1 can be simplified as binodal (9, 10) nets with total Schläfli symbol {3^12;4^9;5^6;6^9}{3^18;4^22;5^5}.Figure optionsDownload full-size imageDownload as PowerPoint slide
