140. Trinuclear double helicates of iron(II) and nickel(II): Self-assembly and resolution into helical enantiomers

Article abstract of DOI:10.1002/hlca.19960790615

The synthesis of the linear tris[terpyridine] 1 with three tridentate binding sites is described. The reaction with metal ions of octahedral coordination geometry, such as Fe^II or Ni^II, leads to the self-assembly of trinuclear complexes [M₃(I)₂]⁶⁺, which display properties in agreement with a double helical structure. The trinuclear iron(II) helicate has been resolved into its enantiomers.
