摘要：

Two-electron reduction of [(η5-C5H4Me)4Fe4(μ3-CH)2(μ3-CO)2](PF6)2 (1) results in the coupling of two methylidyne ligands to form (η5-C5H4Me)4Fe4(HCCH)(μ3-CO)2 (2), the two-electron oxidation of which reproduces 1. Structures of 1 and 2 were determined by X-ray diffraction analysis. Copyright © 2004 American Chemical Society.
