Totally tubular: A linear M8L48+ receptor, which binds tightly and selectively to the dicyanoaurate anion, was assembled from simple organic subcomponents and copper(I) ions. The guest complex is not bound unchanged, but instead is transformed into a longer linear complex where two dicyanogold units are bridged by a central cation of copper/silver (see scheme). This complex optimally fills the cavity of the receptor but is not observed in the absence of the host.
