Size does matter : When treated with Me 2 AlCl, highly soluble bis(aluminate) complexes [Cp*Ln(AlMe 4 ) 2 ] (Ln=Y, La, Nd; Cp*=C 5 Me 5 ) undergo intrinsic alkyl/chloro ligand‐exchange reactions to give products of variable Ln nuclearity, depending on the size of the Ln III metal. The reproducible formation of Y 2 Al 2 , La 6 Al 4 , and Nd 5 Al heterobimetallic alkyl clusters leads to novel AlMe 4 coordination modes (see picture: La 6 Al 4 cluster).
