Abstract

Abstract : A bis-bidentate ligand forms a hexanuclear circular helicate which results in a 3-dimensional honeycomb-like polymer via argentophilic interactions. Abstract : This work shows how multiple non-covalent interactions are employed to control metallosupramolecular architectures and we demonstrate that a ligand, which contains two bidentate domains separated by a ArOH spacer, forms a mesocate when complexed with Ag(i ). However, changing this to an ArOCH2 CH2 Ph spacer unit results in a 1-dimensional helical polymer upon reaction with the same cation. Reaction of Ag(i ) with the ArOMe derivative gives a hexanuclear circular helicate which forms inter-assembly Ag⋯Ag interactions resulting in a 3-dimensional honeycomb-like polymer of hexanuclear circular helicates.
