Abstract
This thesis describes the synthesis of a trimetallic RuII complex [RuII(bpy){(bpyrm)RuII(NH3)4}2](PF6)6 and its bimetallic analog [RuII(bpy)2(bpyrm)RuII(NH3)4](PF6)4. The trimetallic species was designed to be the first in a series of complexes where the reduction potential of the "bridging" complex could be varied (relative to the "terminal" sites) through systematic variation in the metal (M) and/or ligand (LL) … Generation of the [RuII-MII-RuIII] "mixed-valence" complex would then allow observation of "end-to-end" intervalence charge transfer (IVCT) as a function of bridge potential.The initial bi- and trimetallic complexes were synthesized and characterized. In addition, the [2,3] and [3,2,3] "mixed-valence" forms of these complexes were generated and studied. However, a persistent impurity, originating from a side reaction of one of the starting materials, made it difficult to generate the target [2,2,3] mixed-valence form of the trimetallic species. Rigorous attempts to purify the complexes are described in detail.
