Three Silver(I) Coordination Polymers Based on Pyridyl Ligands and Auxiliary Carboxylic Ligands: Luminescence and Efficient Sensing Properties.

Easily producible sensors for harmful industrial waste compounds are of significant interest for both human health and the environment. Three novel coordination polymers, [Ag(μ-aca)(μ-bztpy)] (), [Ag(μ-bza)(μ-bpa)] (), and [Ag(μ-aca)(μ-bpa)]·EtOH·2HO (), were assembled in this study by reactions using Ag as a node with the pyridyl ligand 1,2,4,5-tetrakis(4-pyridyl)benzene (bztpy) or 9,10-bis(4-pyridyl)anthracene (bpa) and an auxiliary chelating carboxylic ligand. Single-crystal X-ray structural analyses revealed that compound has a 3D framework consisting of 1D [Ag(aca)] chains and bztpy linkers, while and have 2D layered structures consisting of binuclear Ag-carboxylate units and bpa linkers, respectively.
