  hindered nature of the L′ site of the bridging ligand. Electrochemical studies show that a given metal ion is slightly easier to oxidize when in the L co-ordination site, but the difference in the properties of the two moieties of the LL′ bridging ligand is much smaller than difference in the properties of RuII and OsII, so that in the mixed-metal complexes Ru–LL′–Os and the metal easier to oxidize is always

  Reaction of the binucleating compound 2,2':3',2'':6'',2''-quaterpyridine (HL), which normally acts as a bis(bipyridyl) ligand with two N,N-bidentate binding sites, with 2 equivalents of [Ru(terpy)Cl3] (terpy = 2,2':6',2''-terpyridine) in the presence of N-methylmopholine afforded the unusual binuclear complex [Cl(terpy)Ru(mu-L)Ru(terpy)][PF6]2 1 in which L is acting as an N,N-bidenate donor to one metal and an N,N,C-cyclometallating terdentate donor to the other. One of the pyridyl residues is therefore acting as an N-donor to one ruthenium(II) centre and a C-donor to the other via the C4 position. Complex 1 was fully characterised by elemental analysis, H-1 NMR (including correlation) and fast-atom bombardment mass spectrometry. Cyclic and square-wave voltammetry shows two reversible one-electron metal-centred oxidations at potentials consistent with the metal co-ordination environments, and the electronic spectrum is also consistent with the complex formulation.
