The cover picture shows , in the background, the contact area and charge distribution of the π‐complex between electron‐rich benzene and electron‐deficient hexafluorobenzene. Besides hydrogen bonding (including CF ··· H interactions), this interaction represents a major structure‐controlling force in the crystal formation of compounds containing electron‐deficient pentafluorophenyl as well as more electron‐rich aromatic groups as substituents. Two examples of this interaction in crystal structures are shown in the foreground of the picture. Details are discussed in the article by M. Albrecht, K. Rissanen et al. on 3235 ff .
