Figure 1

Solid-state (super)structure of the copper-complexed [2]pseudorotaxanate [1•Cu]·PF6 in (a) ball-and-stick and (b) space-filling representations. The copper(I)-complex is distorted significantly from ideal tetrahedral geometry on account of the [π⋯π] stacking interactions between one of the phenoxy moieties of the ring and the phenanthroline ring system in the thread component. The hydrogen atoms and counterions have been omitted for clarity.
