Communication of metal ions in the dinuclear ruthenium complexes containing 4,4′-bipyridine, 1,4-diisocyanobenzene, and pyrazine bridging ligands: Synthesis, characterization and structure determination

The dinuclear complexes [{Ru(bipy)(terpy)}2(μ-L)](PF6)4 show an increase of metal-metal communication by changing the bridging ligand L from 4,4′-bipyridine to 1,4-diisocyanobenzene to pyrazine.
