Self-assembly of two discrete polynuclear iron(II) metallomacrocycles from a ligand containing two 2,2′:6′, 2-terpyridine binding domains

The homoditopic ligand L contains two tpy metal-binding domains and reacts with iron(II) chloride to form two multinuclear metallomacrocycles having [3 + 3] and [4 + 4] metal-ligand stoichiometries. (C) 2003 Elsevier Science B.V. All rights reserved.
