摘要：

The reaction of [Fe(N(SiMe3)2)2] with thiols RSH, elemental sulfur, and neutral ligands L (with sulfur donor atoms, e.g. thiourea derivatives) gives [Fe4S4(SR)2L2] clusters in high yields. The structure of [Fe4S4(2.4.6-(C3H7) 3C6H2-S)2(dpdmi)2] (dpdmi: diisopropyldimethyl-imidazolthion) was determined by X-ray crystallography. When [Fe4S4I4]2- is reacted with a large excess of PMePh2 or PMe2Ph [Fe6S6I2(PMePh2)4] and [Fe6S6I2(PMe2Ph)4], respectively, are obtained in nearly quantitative yield. Basket-like structures of the [Fe6S6]2+ cores were detected by X-ray structure analysis. While [Fe4S4(SR)4]2- clusters do not react with phosphanes at ambient temperature 2:2 functionalized species like [Fe4S4(SR)2(tmtu)2] lead to basket-type clusters [Fe6S6(SR)2(PR3)4].
