Abstract
Three supramolecular coordination polymers (SCPs) [(AgSCN)(2).L] (L = 4,4'-bipyridine (bpy) (1), trans-1,2-bis(4-pyridyl)ethylene (tbpe) (2) and phenazine (phenz) (3)) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Synthesis was affected in H2O/acetonitrile/NH3 media at room temperature. The bpy, tbpe and phenz bipodal ligands adopt different conformations which would affect the skeleton of the (AgSCN)(n) building blocks that allow the interconnection of the (AgSCN)(n) fragments and propagation of the network structure in three dimensions. Supramolecular interactions such as hydrogen-bonding, argentophilic interaction and pi-pi stacking play an important role in the assembly of these coordination polymers. (C) 2009 Elsevier Ltd.
