Reactions of the di-iron complex [Fe₂(μ-S)₂(CO)₆]^2- with carboxy-functionalized dihalide derivatives (XCH₂)₂R (X = Cl, R = NC₆H₄CH₂CO₂CH₃; X = Br, R = C₆H₃COOH, C₆H₃COON(COCH₂)₂) gave new functionalized dithiolate di-iron complexes [Fe₂(μ-SRS)(CO)₆] (R = (CH₂)₂NC₆H₄CH₂CO ₂CH₃ (1), (CH₂)₂C₆H₃COOH (2), (CH₂)₂C₆H₃COON(COCH ₂)₂ (3)) in low yields. The azadithiolate complex 1 has been characterized by a single crystal X-ray diffraction analysis and studied by electrochemical methods.
