Conventional and metal-directed synthesis of homodinuclear and heterotrinuclear complexes of homoditopic and heteroditopic ligands incorporating bpy and tpy metal-binding domains
摘要:
Strategies for the preparation of multinuclear complexes containing homoditopic and heteroditopic ligands based upon 2,2$-bipyridine (bpy) and 2,2:6$,2$$-terpyridine metal binding domains are presented. Both conventional approaches based upon preparation of a free ligand and subsequent coordination and metal-directed reactions of coordinated ligands are utilized in the various strategies. A representative series of complexes of these ligands has been prepared. (c) 2005 Elsevier Ltd. All rights reserved.
