摘　　要：The title complex,（μ-pdt）Fe_2（CO）_5（Ph_2PCH_3）（pdt = SCH_2CH_2CH_2S）,was obtained by the reaction of the parent complex（μ-pdt）Fe_2（CO）_6 with Ph_2PCH_3 and Me_3NO·2H_2O in good yield（90%）. The title complex was characterized by IR,~1H NMR,^（31）P{~1H} NMR and ^（13）C{~1H} NMR spectroscopy as well as by single-crystal X-ray diffraction analysis. The molecular structure shows that the title complex contains a butterfly diiron propanedithiolate cluster with five terminal carbonyls and a monophosphine ligand Ph_2PCH_3. The crystal packing diagram reveals that intermolecular C H···O hydrogen bonds between CH_2 and carbonyls,π-π stacking interactions and van der Waals＇ interactions stabilize the solid state to form a three-dimensional network.The title complex,（μ-pdt）Fe_2（CO）_5（Ph_2PCH_3）（pdt = SCH_2CH_2CH_2S）,was obtained by the reaction of the parent complex（μ-pdt）Fe_2（CO）_6 with Ph_2PCH_3 and Me_3NO·2H_2O in good yield（90%）.
