The ternary palladium π-adduct of corannulene and benzene, [Pd6Cl12·(C20H10)2·(C6H6)2]·C6H6 (1), has been prepared by reacting the cubic Pd6Cl12-cluster with C20H10 in benzene. It was structurally characterized to reveal η1-binding of Pd6Cl12 to a hub C-atom of the convex surface of corannulene (Pd⋯C, 3.085(3) Å) and its η6-complexation to benzene (Pd⋯Ccentroid, 3.431(3) Å). The behavior and persistence of 1 in some aromatic solvents has been revealed by UV–vis and 1H NMR spectroscopy studies.
