摘　　要：用P（SR）Cl2和P（SR′）3作n-酸配体,分别与Fe3（CO）9（μ3-S）2进行取代反应,得到6种新的一取代产物Fe3（CO）8（μ3-S）2L和3种新的二取代产物Fe3（CO）7（μ3-S）2L2,并对它们进行了IR、1H NMR和MS表征,测定了其中一种取代物Fe3（CO）8（μ3-S）2[P（SC6H5）Cl2]的分子和晶体结构。Six new mono- and three di-substituted derivatives of Fe3(CO)9(μ3-S)2 with P(SR)C12 and P(SR')3 were synthesized. They have the formulas; Fe3 (CO)8 (μ3-S)2L [L = P (SC6H5) C12, P(SC2H5)C12, P(SC3H7)C12, P(SC2H5)3, P(SC6H13)3, P(SC3H7)3] and Fe3(CO)7(μ3-S)2L2[L = P(SC6H5)C12, P(SC2H5)3, P(SC6H5)3] , respectively.The nine new compounds were characterized by elemental analysis and IR, 1H NMR.MS spectra and the structure for Fe3(CO)8(μ-S)2[P(SC6H5]Cl2] was determined by means of four cycle diffractome-ter.
