Reaction of Cp₃Fe₄(CO)₄(C₅H₄CHO) (1) and 2-acetylpyridine produces Cp₃Fe₄(CO)₄(C₅H₄CH═CHC(═O)(2-C₅H₄N)) (2) and Cp₃Fe₄(CO)₄(C₅H₄CH(CH₂C(═O)(2-C₅H₄N))₂) (3), which can convert to Cp₃Fe₄(CO)₄(4′-C₅H₄-2,2′:6′,2′′-terpyridine) (4) in moderate yields. Coordination of 4 to Fe(II) and Ru(II) ions afford the double-cluster complexes [(Cp₃Fe₄(CO)₄(4′-C₅H₄-2,2′:6′,2′′-terpyridine))₂Ru](PF₆)₂ (5) and [(Cp₃Fe₄(CO)₄(4′-C₅H₄-2,2′:6′,2′′-terpyridine))₂Fe](PF₆)₂ (6), respectively. Compounds 4−6 have been characterized by mass, NMR, and UV−vis spectroscopy, and the structure of 4 was determined by an X-ray diffraction study.
