Heteroditopic ligands containing a 2,2 '-bipyridine and a 2,2 ': 6 ', 2 ''-terpyridine moiety and their ruthenium tris(bipyridine)-like complexes

Two novel heteroditopic ligands in which the bidentate 2,2'-bipyridine (bpy) ligand is covalently linked to one or two 2.2' : 6',2''- terpyridine (terpy) terdentate ligands have been prepared and characterized. The synthesis and the physico-chemical features of their corresponding complexes in which the bpy site is complexed by a ruthenium moiety are also reported. (C) 2002 Elsevier Science B.V.
