The synthesis and structural analysis of a macrocyclic exo-ditopic lig
and bearing two 2,2'-bipyridine units interconnected at the 4 and 4' p
ositions by two -(CH2)(2)Si(CH2)(2)-spacers and of its acyclic analogu
e is achieved; for both compounds ruthenium homobinuclear complexes we
re prepared; for the complex obtained with the cyclic ligand, both dia
stereoisomers were separated and the structure of the meso form was el
ucidated by X-ray analysis.
