This is the authors' abstract. We don't add key points for this paper.

The complexes [{(X)PdN(Cy) C(H)C 6 H 2 C(H) N(Cy)Pd(X)} 2 {(μ-Ph 2 PC 5 H 4 FeC 5 H 4 PPh 2 } 2 ] (X = Cl ( 3 ), X = Br ( 4 )) have been prepared by reaction of [(X)PdN(Cy) C(H)C 6 H 2 C(H) N(Cy)Pd(X)] n (X = Cl ( 1 ), X = Br ( 2 )) with 1,1‘-bis(diphenylphosphino)ferrocene (dppf), and they were characterized by elemental analysis (C, H, N) and by 1 H and 31 P{ 1 H} NMR spectroscopy in CDCl 3 . The compounds are arranged as hexanuclear supramolecular cages containing two different metals, palladium and iron. The crystal structure of complex 4 was determined by X-ray diffraction studies.
