A novel dinuclearruthenium(II) complex containing two ortho-xylylene-linked bis(NHC) ligands (NHC = N-heterocyclic carbene) has been synthesized via transmetalation from a silver-NHC complex. Each ruthenium atom in the dinuclearcomplex is chelated through the two carbene carbon atoms and, unusually, an η2-bound xylylene ring, two separate bis(NHC) units being linked by a Ru(μ-Cl)3Ru core.
