The ability of the imine PyCH═N-CH2 Py (Py = 2-pyridyl, bpi) to behave as a heteroditopic ligand, which is suitable for creating two separate compartments to host metals in different oxidation states, has been developed by studying the reactions of the mixed-valence complexes [(cod)M-Ι (μ-bpi)MΙ (cod)] (M = Rh, Ir) with [M'(Cl)2 (PPh3 )2 ] (M' = Pd, Ni). The results depend on the molar ratio of the reagents used (1:1 or 1:2) to give the heterometallic complexes {d10 -M',d8 -M}-[(PPh3 )(Cl)M'0 (μ-bpi)MΙ (cod)] (Pd,Rh, 4 ; Pd,Ir, 5 ; Ni,Rh, 8 ; Ni,Ir, 9 ) and the two-electron mixed-valent compounds [(PPh3 )(Cl)M'0 (μ-bpi)M'ΙΙ (Cl)] (M' = Ni, 10 ; Pd, 11 ), respectively...
