Abstract

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.
