Despite the distance of four para ‐phenylene units between them, the Ru centers in complex 1 are strongly coupled. This system, in which two aromatic rings separate the Ru‐coordinating benzene anions, has the same strong metal‐metal coupling as the isoelectronic system in which two coordinating pyridine rings are directly connected. The strong coupling in 1 can be explained by the efficient interaction of the energetically similar metal and ligand orbitals.
