摘要
用Fe3（CO）9（μ3-S）2和P（YR）3（Y=O,S）在温和条件下反应,获得8种一取代和二取代新的簇合物,发现Fe3（CO）9（μ3-S）2和P（OR）3有新的二取代方式,进而合成了另8种具有新的结构的二取代簇合物。对这些簇合物进行了元素分析和IR、1H NMR、MS表征,并对Fe3（CO）7（μ2-CO）·[P(O-cyclo-C6H11]（μ3-S）（Ⅷ）进行了X光单晶结构分析。
The reactions of Fe3(CO)9(μ3-S)2 with P(YR)3(Y=O, S) at mild conditions were investigated. Eight mono- and di-substituted new compounds were synthesized; IX-XVI: Fe3(CO)8[P(OR)3] (μ3-S)2(R=iso-C3H7, sec-C4H9, iso-C4H9, n-C6H13, cyclo-C6H11), Fe3(CO)8[P(S-nC3H7),](μ3-S)2, Fe3(CO)7[P(O-secC4H9)3]2(μ3-S)2 and Fe3(CO)7[P(S-nC3H7)3]2(μ3-S)2. Also , eight novel compounds with new structure were synthesized: Ⅰ -Ⅷ: Fe3(CO)8[P(OR)3(μ3--S) (R = n-C3H7, iso-C3H7, n-C4H9, sec-C4H9, iso-C4H9,n-C5H11, n-C6H13, cyclo-C6H11). The features of this series clusters are dissociated with a μ3-S and a terminal CO changed to a μ2-CO during the reaction. The Corresponding Fe3 framework changes from opened-triangle to closed-trangle. Ⅰ -ⅩⅥ have been charac-terzed by IR, 1H NMR and some by mass spectroscopy. The molecular structure of Fe3(CO)8[P(O-cyclo-C8Hn)3]2(μ3-S) has been determined by single crystal X-ray diffractomer.
