Various polypyridyl organometallic complexes of Ru(II) and other d4-transition metals have been subjects of recent study. Interest in these systems stems from the possible application of their metal-to-ligand charge transfer (MLCT) excited states in energy conversion $processes.1$ We have prepared and investigated spectroscopically $(bpy)3Ru(II)(bpm),(phen)2Ru(II)(bpm),[(bpy)3Ru(11)]2(bpm)$, and $[(phen)2Ru(II)]2,bpm$, where bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, and bpm = 2,2'-bipyrimidine. The monometallic complexes show intense absorption in the blue region of the spectrum, whereas the lowest energy MLCT absorption band of the bimetallic complexes is red shifted. The bimetallic complexes have many MLCT transitions in the visible region. Resonance Raman spectroscopy has been utilized to characterize and assign these transitions.
