Multicomponent Self‐Assembly: Spontaneous Formation of a Cylindrical Complex from Five Ligands and Six Metal Ions

In one fell swoop eleven building blocks— five ligands and six metal ions—self‐assemble to give the discrete Cu 1 complex 1 shown schematically on the right (phenyl substituents at the two central ligands and the methyl substituents at the three outer ligands have been omitted). The formation of 1 demonstrates how molecular self‐organization can be controlled by the design and selection of the individual components to provide unusual structures. In the case of 1 the bridging ligands define a cylindrical cavity. • = copper(I) atom.
