Fe(II)双酰胺Fe{N(SiMe3)(2)}(2)与元素硫反应，直接进入端酰胺基团Fe4S4(N(SiMe3)214(1)和Fe2S2{N(SiMe3)(2)}(2)(2)(Tmtu)(2)(2))的[FC2S2]和[Fe4S4]簇合物。四聚立方烷簇合物1在循环伏安曲线上表现出一个可逆过程和一个准可逆过程，而二聚菱形配合物2表现出一个不可逆还原过程。
The reaction of iron(II) bis-amide Fe{N(SiMe3)(2)}(2) with elemental sulfur afforded a direct entry to new [FC2S2] and [Fe4S4] clusters with terminal amide groups, Fe4S4(N(SiMe3)214 (1) and Fe2S2{N(SiMe3)(2)}(2)(tmtu)(2) (2), whose structures have been determined by X-ray crystallography. Tetrameric cubane cluster 1 exhibits one reversible and one quasireversible processes in the cyclic voltammetry, whereas dimeric rhombus complex 2 reveals one irreversible reduction process.
