The 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 D 3d 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).
