Coordinatively unsaturated diruthenium complexes, [(η5-C5Me5)Ru(μ2-iPrNC(Me)=NiPr)Ru(η5-C5Me5)]+, of which crystallography revealed structures bearing a bridging amidinate ligand perpendicular to the Ru-Ru axis, were synthesized by anion exchange of [(η5-C3Me5(Ru(μ2-iPrNC(Me)=NiPr)Ru(η5-C5Me5)]+Br- by weakly coordinating anions. Variable-temperature NMR showed rapid motion of the bridging amidinate ligand. The coordinatively unsaturated nature of the cationic complexes provides their high reactivity toward a series of two electron donor ligands. Oxidative addition of molecular hydrogen occurred to give [(η5-C5Me5)Ru(μ2-iPrNC(Me)=NiPr)(μ-H)Ru(η5-C5Me5)(H)]+, which was isolated and characterized.
