The cover picture shows the pictogram of the complex tetranuclear iron( III ) cluster [Fe 4 (L 1 ) 4 ]. With the growing size of supramolecular systems, the fundamental question, how to visualize science, becomes more and more challenging. In the case of [Fe 4 (L 1 ) 4 ], this difficult task was solved by placing four Fe III centers (silver balls) in the vertices of a tetrahedron. The four tris‐bidentate ligands (L 1 ) 3− (golden tridents) are located above the triangular faces and linked to three Fe III cations, each. The [Fe 4 (L 1 ) 4 ] cage has idealized T‐molecular symmetry. Thus, the four iron( III ) centers have the same chirality (all Δ or Λ ). Hence, [Fe 4 (L 1 ) 4 ] generates homoconfigurational racemic crystals. Further details of the preparation and structure of tetrahedral [Fe 4 (L 1 ) 4 ], together with antiprismatic [Fe 6 (L 2 ) 6 ], are reported by R. W. Saalfrank, K. N. Raymond et al. on p. 493 ff.
