48_21/2009Cover Picture: Substituent-Free Gallium by Hydrogenolysis of Coordinated GaCp*: Synthesis and Structure of Highly Fluxional [Ru2(Ga)(GaCp*)7(H)3] (Angew. Chem. Int. Ed. 21/2009)

Soft skin, hard core ... is the basic principle for the formation of a nano-alloy from molecular precursors. The co-hydrogenolysis of ruthenium complexes in presence of GaCp* gives the isolable key intermediate [Ru2(Ga)(GaCp*)7(H)3] featuring a substituent-free bridging gallium atom. From this “embryonic” species Ru/Ga phases are formed by complete cleavage of the protective Cp* shell (depicted as an eggshell in the Cover picture), as described by R. A. Fischer et al. in their Communication on page 3872 ff.
