Bowls to balls: Triangular bowl-shaped copper(I) circular helicates based on pyridylimine ligands are assembled by mixing readily available reagents. The bowl-shaped topography of the triangles controls the supramolecular aggregation of four of these units into a chiral tetrameric ball-shaped structure (see picture) held together by face–edge (CH⋅⋅⋅π) π interactions and CH⋅⋅⋅F interactions.
