Bipyrimidine-Bridged Mixed-Metal Trimetallic Complexes of Ruthenium(II) with Rhodium(III) or Iridium(III), {[(bpy)2Ru(bpm)]2MCl2}5+

“…Investigations leading to the design of photochemically and electrochemically active polypyridyl complexes resulted largely from the fact that [Ru(bpy) 3 ] 2+ has a long-lived metal-to-ligand charge transfer (MLCT) excited state and has the ability to undergo facile electron transfer reactions. − Polymetallic systems incorporating Ru II (bpy) 2 fragments have been widely studied. − To bring together metals into a polymetallic system, a variety of bridging ligands are used. − Variation of both metal centers and ligands are possible, leading to a tailoring of the spectroscopic and redox properties of these polymetallic systems. It has been proposed that polymetallic systems could be designed to function as photochemical molecular devices 8e…”

“…2,2‘-Bipyrimidine (bpm) is able to bridge a variety of metal centers and is expected to electronically couple adjacent metal centers in a polymetallic system. 5c,8b,− This coupling is due to bpm's ability to position two metal centers at a distance of ∼550 pm in a fixed orientation which will allow a direct or indirect dπ−dπ interaction 17b. Monometallic complexes containing bpm as a ligand have been synthesized and characterized by a number of research groups with the objective of utilizing them as precursors for polymetallic synthesis.…”
