Linking two bipyridine units by a 1,3-phenylene spacer has provided a novel class of ligand which promotes the spontaneous self-assembly of double helicates upon reaction with transition-metal ions.Interaction with copper(I) or silver(I) resulted in dinuclear double-helical complexes with the metal ions occupying pseudo-tetrahedral co-ordination sites.Reaction with cobalt(II) or nickel(II) acetates gave similar dinuclear double-helical structures with a didentate acetate ligand completing the co-ordination sphere of each metal to give a pseudo-octahedral geometry.The crystal structure of
