摘要
Ｆｅ３（ＣＯ）＿（１２）和取代２，４＿二硫代乙内酰脲反应，得到新的取代物Ｆｅ３（ＣＯ）＿８－［：ＣＮＨＣ（Ｓ）Ｃ（ＣＨ＿３）＿２ＮＨ］（μ＿３－Ｓ）＿２，并进行了ＩＲ、１￣ＨＮＭＲ、ＭＳ表征，测定了它的分子和晶体结构，讨论了杂环卡宾碎片：ＣＮＨＣ（Ｓ）Ｃ（ＣＨ＿３）＿２ＮＨ的取代位置，它是通过卡宾碳原子与Ｆｅ配位。
The reaction of Fe_3 (CO)_(12) with 2,4-dithiohydantion gave a new trinuclear iron carbonyl cluster Fe_3 (CO),_8(μ_3-S)_2[:CNHC(S)(CH_3)_2NH].The ligand[: CNHC(S)C (CH_3)_2NH] is coordinated to iron via carbene carbon. The compound was characterized by elemental analysis,IR,￣1H NMR,and MS spectra,and the structure was determined by X-ray diffraction technique. The geometrical characteristics of the molecular configuration are discussed.
