Double stranded interwound infinite linear silver coordination networkDedicated to G. Ourisson on the occasion of his 75 birthday.

Abstract

Upon self-assembly of a bismonodentate ligand based on two pyridine units interconnected at the para position by a hexaethylene glycol fragment using ester junctions and Ag⁺ cation, a double stranded interwound infinite linear network was obtained in the crystalline phase; the formation of this unprecedented architecture is a result of the loop type conformation of the connector segment which forms a pseudo-crown ether. The loop surounds the metal cation which is linearly coordinated to two pyridines belonging to consecutive units, thus forming the 1-D network.
