Abstract

All change: Complete ligand exchange through the hydrogenation of [Ru(η4-cod)(η6-cot)] in the presence of GaCp* under mild conditions leads to the title complex featuring a “naked” gallium atom bridging two ruthenium centers (see structure: C white, Ga blue, Ru red). This cluster can be considered as a trapped intermediate on the way to mixed-metal nanoparticles; cot=1,3,5-cyclooctatriene; cod=1,5-cyclooctadiene, Cp*=C5Me5.
