| Abstract: | Stable dinuclear transition metal complexes,(η6‐C6H6)2Ru2(L1)Cl2]2+ ( 1 ), (η6‐p‐iPrC6H4Me)2Ru2(L1)Cl2]2+ ( 2 ), (η6‐C6Me6)2Ru2(L1)Cl2]2+ ( 3 ), (η6‐C6H6)2Ru2(L2)Cl2]2+ ( 4 ),(η6‐p‐iPrC6H4Me)2Ru2(L2)Cl2]2+ ( 5 ), (η6‐C6Me6)2Ru2(L2)Cl2]2+ ( 6 ), (η5‐C5Me5)2Rh2(L1)Cl2]2+ ( 7 ), (η5‐C5Me5)2Ir2(L1)Cl2]2+ ( 8 ),(η5‐C5Me5)2Rh2(L2)Cl2]2+ ( 9 ), and (η5‐C5Me5)2Rh2(L2)Cl2]2+ ( 10 ), with the bis‐bidentate ligands 1,3‐bis(di‐2‐pyridylaminomethyl)benzene (L1) and 1,4‐bis(di‐2‐pyridylaminomethyl)benzene (L2), which contain two chelating dipyridylamine units connected by an aromatic spacer, were synthesized. The cationic dinuclear complexes were isolated as their hexafluorophosphate salts and characterized by using a combination of NMR, IR, and UV/Vis spectroscopic methods and mass spectrometry. The solid‐state structure of complex 8 as a representative was determined by X‐ray structure analysis. |
