Cyanogen as a Bridging Ligand—Preparation and Crystal Structure of Polymeric [Ag{(CN)₂}₂]_n[AsF₆]_n with an Undulating Square Cationic Network

Of interest for metal-catalyzed reactions of cyanogen is the structure of complexes containing this pseudohalogen. In the cation 1, the title compound is present in a polymeric network in which each silver atom is surrounded by a square-planar array of nitrogen atoms.
