The cover picture shows the discrete fluoroaluminate anion, AlF 5 2– , with trigonal‐bipyramidal geometry, over the history of fluoroaluminate anions. The structure of AlF 5 2– has been the matter of discussion for 25 years; the data obtained supplements the row of small discrete fluoroaluminate anions. The packing diagram shows that the anions are organized in 1D columns and interconnected by hydrogen bonds formed with water molecules. The determination of the crystal structure has completed the discussion on the ligand close packing model of the geometry of fluorides of third‐period elements (Si, P, and Al). Details are discussed in the Short Communication by K. Matsumoto et al. on p. 5306 ff . For more on the story behind the cover research, see the Cover Profile .
