The cover shows a space‐filling model (drawn with the SCHAKAL program) of a tris(arene) gallium complex with a novel mode of coordination: gallium( I ) is enclosed in the cavity formed by the three benzene rings of [2.2.2]paracyclophane. This is the first example of a metal complex containing three centrically bound neutral arene ligands. The central atom has no less than 19 atoms in its first coordination sphere—18 C atoms of the benzene rings and one Br atom of the anion GaBr 4 − , which forms a weak contact. Further details are reported by H. Schmidbaur et al. on page 338 ff.
