26_07/1987The cover shows a model of the structure of a Cu2-complex with two peripheral 30-membered rings concatenated with a 44-membered central ring. The complex consists of two (phenanthroline)2Cu+ 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-(CH2O)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-CH2-C4-CH2-O-phenylene). These ligands and bridges (yellow) from the central ring of the Cu2-[3]-catenate. Further details of this fascinating globular molecule are reported by J.-P. Sauvage et al. on p. 661ff.
