Structural Diversity and Argentophilic Interactions\nin One-Dimensional Silver-Based Coordination Polymers

Abstract

A series\nof new one-dimensional coordination polymer materials, based on Ag­(I)–N\nbond formation, has been synthesized and structurally characterized\nby single crystal X-ray diffraction. Reactions between the poly-monodentate\nligands based on (<i>1E</i>,<i>1</i>′<i>E</i>′)<i>-N</i>,<i>N</i>′<i>-</i>(-bis­(1-pyridin-3-yl)­methanimine and Ag­(I) salts give products\nthat feature simple coordination chains or metallacyclic- and tape-based\nstructures. For the simple chains these are as either isolated units,\nor assembled in dimeric and tetrameric arrangements through intermetallic,\nargentophilic interactions. However, crystal packing effects and solvent\ninclusion are found to readily disrupt this type of bonding. Density\nfunctional theory calculations provide an assessment of the bond order\nand the influence of anion binding on these interactions.
