A μ‐η 4 :η 4 ‐arene bridge was detected for the first time in the triple‐deckers 1 (arene = benzene, toluene, o ‐, m ‐, p ‐xylene, cumene). This bridging ligand deviates substantially from planarity in the X‐ray crystal structure analysis of the cumene derivative (see picture) and is already substitutionally labile at room temperature. It can be exchanged for other π‐perimeter compounds without affecting the molecular structure.
