The cover picture shows a stylized view of the four interpenetrating three‐dimensional networks formed by autocomplementary hydrogen bonding of neutral, racemic [Co III (2,2′‐biimidazolate) 3 ] molecules (top and bottom, view along b axis) and the arrangement of helices obtained with enantiomerically pure D ‐[Co III (2,2′‐biimidazolate) 3 ] (center). Popular motifs as they are with scientists today doing supramolecular chemistry or crystal engineering, these patterns can be traced back much further in time. They were popular motifs for graphic designers in Viking, Saxon, and Celtic cultures in which the interlacing nets were believed to trap evil. The cover takes its inspiration from a "carpet page" in a 7th century gospel book known as the "Book of Durrow". These structures, including the porous nature of the three‐dimensional net, are discussed in detail in the article by L. Öhrström et al. on p. 4805 ff. Illustration by K. Larsson. The horses have no chemical significance.
