Redox reactions, substitutions, and metalations are reported for the iron carbido sulfide [Fe₆C(CO)₁₄(S)]^2– ([1]^2–). Dianion [1]^2– oxidized to [Fe₆C(CO)₁₆(S)]⁰ ([2]⁰) upon treatment with of [Fe(C₅H₅)₂]BF₄ or HBF₄ (H₂ formation) under an atmosphere of CO. Reaction of [2]⁰ with tBuNC gave [Fe₆C(S)(CO)₁₃(tBuNC)₅], consisting of Fe₅C(CO)₁₃ and [Fe(tBuNC)₅]²⁺ subunits linked by a µ₃‐S^2–. The Fe₇CS cluster [Fe₇C(CO)₁₇(S)]^2– formed upon treatment of (Ph₄P)₂[1] with Fe(benzylideneacetone)(CO)₃. The Fe₇ species is an edge‐fused cluster with [Fe₆C(CO)₁₀(µ‐CO)₄] and Fe(CO)₃ subunits joined by µ₃‐S and two Fe–Fe bonds. The analogous reaction using Mo(CO)₄(norbornadiene) gave [MoFe₆C(CO)₁₈(S)]^2–. In this cluster, the Mo center is located in the octahedral subunit. Treatment of [1]^2– with SO₂ afforded [Fe₆C(S)(SO₂)(CO)₁₃]^2–. This cluster features an Fe₆C core decorated with µ₃‐S and µ₂‐SO₂ ligands. These experiments were undertaken in an effort to connect organometallic clusters to FeMoco.

[Fe6C（CO）14（S）] 2–的反应：团簇生长，氧化还原，硫化

据报道，硫化碳铁[Fe ₆ C（CO）₁₄（S）] ^2–（[ 1 ] ^2–）的氧化还原反应，取代和金属化。在用[Fe（C ₅ H ₅）₂ ] BF ₄或HBF ₄（H ₂形成）处理后，Dianion [ 1 ] ^2-氧化为[Fe ₆ C（CO）₁₆（S）] ⁰（[ 2 ] ⁰））在CO气氛下。[ 2 ] ⁰与t BuNC的反应得到[Fe₆ C（S）（CO）₁₃（t BuNC）₅ ]，由Fe ₅ C（CO）₁₃和[Fe（t BuNC）₅ ] ²⁺亚基组成，由µ ₃ -S ^2–连接。Fe ₇ CS团簇[Fe ₇ C（CO）₁₇（S）] ^2–在用Fe（亚苄基丙酮）（CO）₃处理（Ph ₄ P）₂ [ 1 ]时形成。Fe ₇物种是具有[Fe ₆ C（CO）₁₀（µ-CO）₄的边缘融合簇。]和Fe（CO）_3个亚基通过µ ₃ ‐S和两个Fe–Fe键连接。使用Mo（CO）₄（降冰片二烯）进行的类似反应得到[MoFe ₆ C（CO）₁₈（S）] ^2–。在该簇中，Mo中心位于八面体亚基中。用SO ₂处理[ 1 ] ^2–得到[Fe ₆ C（S）（SO ₂）（CO）₁₃ ] ^2–。该簇的特征是Fe ₆ C磁芯装饰有µ ₃ ‐S和µ ₂ ‐SO ₂配体。进行这些实验是为了将有机金属簇连接到FeMoco。
