Abstract
A series of ditopic ligands bearing terpyridyl and polyamine coordination sites have been prepared. Complexes with RuII bound to the terpyridyl sites of many of these ligands have been prepared. RuII complexes of these ligands appear vulnerable to nucleophilic displacement of the polyamine portion of the ligand by BH4 –. A limited study of the coordination chemistry of the polyamine portion of the RuII complexes has been conducted, including the synthesis and characterization of RuII–CoIII heterodinuclear complexes in which the CoIII centre is coordinated by a cyclam macrocycle. The CoIII centre in these systems is unexpectedly labile – it can be removed from the polyamine upon treatment with ethane-1,2-diamine.
