Cover Picture (Angew. Chem. Int. Ed. Engl. 24/1997)

36_24/1997The cover picture might resemble a Christmas decoration, as one can expect at this time of the year, but is in fact a space-filling model of the structure of an octadecairon(III) complex that shows idealized D3d symmetry. Cyclic molecules have always fascinated chemists—see for example the Highlight on p. 348 in issue 4 of this year—and there are many molecular counterparts of everyday ring-shaped objects. Multinuclear macrocyclic transition metal complexes can have interesting characteristics. Antiferromagnetic interactions occur between the 18 high-spin iron(III) centers in the molecular 18-wheeler shown in the cover picture. More on the largest known ring-shaped iron(III) compound is reported by S. J. Lippard et al. on p. 2774 ff (computer graphics: Felice Frankel, Massachusetts Institute of Technology).
