Abstract

original image

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.
