The cover picture shows the crystal structure of a unique supramolecular architecture consisting of five tris(bispyridine) ligands (shown in different colors) wrapped around five Fe II ions (purple) in a double‐helical fashion and closed to form a torus around a central chloride ion (green). This circular helicate is an analogue of circular DNA. Its formation also points to the possibility of designing self‐assembling systems that generate receptors for specific substrates from a collection of suitable ligands and metal ions. More about the circular helicate and the concept of “virtual combinatorial libraries” is reported by J.‐M. Lehn et al. on p. 1838 ff.
