Suitably substituted diazines also form chelate complexes, e.g. 2,3,5,6-tetrakis(a-pyridyl)pyrazine yields red tridentate complexes with Fe11. In the fast development of metallosupramolecular chemistry, many other polydentate ligands, based on 2,2 -bipyridyl units, have been obtained and studied (94CI(L)56). Thus, two molecules of oligopyridine (58) interact with various metal ions (Fe2+, Co2+, Cu2+ etc.) to form a double-helical [M2L2]4+ complex in which each metal is bonded to a tridentate region from each ligand.
