To develop the butterfly Fe/E (E = S, Se) cluster chemistry, the following four types of new butterfly Fe/E cluster complexes have been synthesized and structurally characterized. The first type of such complexes involves the linear type of (diphosphine)Pt-bridged double-butterfly Fe/E clusters [(μ-PhSe) (μ-S=CS)Fe₂(CO)₆]₂[Pt(diphosphine)] (1–3, diphosphine = dppe, dppv, dppb), while the second type of complexes involves the linear type of butylene-bridged double-butterfly Fe/E clusters [μ-Se(CH₂)₄Se-μ][(μ-R)Fe₂(CO)₆]₂ (4–6, R = PhCH₂SC=S; PhNHC = S; PhC = NC₆H₄Me-p). More interestingly, the third and fourth types of complexes include the macrocyclic type of (diphosphine)Pt-bridged double-butterfly Fe/E clusters [μ-Se(CH₂)₃Se(CH₂)₃Se-μ][(μ-S=CS)Fe₂(CO)₆]₂[Pt(diphosphine)] and the macrocyclic type of quadruple-butterfly Fe/E clusters {[μ-Se(CH₂)₃Se-μ][(μ-S=CS)Fe₂(CO)₆]₂}₂[Pt(diphosphine)]₂ (7a,b−8a,b, diphosphine = dppe, dppv), respectively. While the possible pathways for production of the four types of new butterfly Fe/E complexes are briefly described, their structures are characterized by elemental analysis and various spectroscopic methods, and particularly for their representatives by X-ray crystallography.

为了发展蝶形Fe / E（E = S，Se）簇化学，已经合成了以下四种类型的新型蝶形Fe / E簇络合物并对其结构进行了表征。第一类此类络合物涉及线性类型的（二膦）Pt桥连双蝶形Fe / E团簇[（μ-PhSe）（μ-S= CS）Fe ₂（CO）₆ ] ₂ [Pt（二膦） （1-3，二膦= DPPE，dppv，DPPB），而第二类型的复合物包括的线性类型丁烯-桥连的双蝴蝶的Fe / E簇[μ-SE（CH ₂）₄硒μ] [ （μ-R）Fe ₂（CO）₆ ] ₂（4–6，R = PhCH ₂SC = S; PhNHC = S; PhC = NC ₆ H ₄ Me- p）。更有趣的是，在第三和第四类型的复合物包括大环型的（二膦）合铂-桥连双蝴蝶的Fe / E簇[μ-SE（CH ₂）₃硒（CH ₂）₃硒μ] [（μ -S = CS）的Fe ₂（CO）₆ ] ₂ [PT（二膦）]和大环型四重蝴蝶的Fe / E簇{[μ-SE（CH ₂）₃硒μ] [（μ-S = CS）Fe ₂（CO）₆ ] ₂ } ₂ [Pt（二膦）] ₂（7a，b-8a，b，二膦= dppe，dppv）。虽然简要描述了生产四种新型蝶形Fe / E络合物的可能途径，但它们的结构通过元素分析和各种光谱方法进行了表征，尤其是通过X射线晶体学表征。
