A ferrocene-based biscatecholamide ligand was prepared and investigated for the formation of metal-ligand supramolecular assemblies with different metals. Reaction with Ge(IV) resulted in the formation of a variety of Ge(n)L(m) coordination complexes, including [Ge(2)L(3)](4-) and [Ge(2)L(2)(mu-OMe)(2)](2-). The ligand's ability to swivel about the ferrocenyl linker and adopt different conformations accounts for formation of many different GenLm species. This study demonstrates why conformational ligand rigidity is essential in the rational design and directed self-assembly of supramolecular complexes.
