The cover shows a model of the structure of a Cu 2 ‐complex with two peripheral 30‐membered rings concatenated with a 44‐membered central ring. The complex consists of two (phenanthroline) 2 Cu + complexes which are easily recognizable by their Cu (purple) and N (blue). One phenanthroline ligand in each of the two complexes contains a phenylene‐O‐(CH 2 O) 5 ‐phenylene bridge; one of these ligands (with its bridge) is shown in green, the other in light brown (red: O). The two unbridged phenanthroline ligands are connected together by two “straight chains” (phenylene‐O‐CH 2 ‐C 4 ‐CH 2 ‐O‐phenylene). These ligands and bridges (yellow) from the central ring of the Cu 2 ‐[3]‐catenate. Further details of this fascinating globular molecule are reported by J.‐P. Sauvage et al. on p. 661ff.
