本文合成了以环戊烯配位的羰基钌簇合物Ru~3(CO)~9(C~5H~6), 用IR, ^1H NMR,^1^3C NMR和元素分析等方法对此簇合物进行了结构表征, 配体环戊烯的双键被打开并且分别配位于金属钌原子所组成的平面上和下, X射线进一步肯定了以上结论, 簇合物为单斜晶系, 空间群为P2~1/a, a=1.6498(8), b=1.3221(5),c=1.7330(6)nm, β=91.54(3)°, V=3.779(3)nm^3, Z=8, μ=23.5cm^-^1,Dc=2.18g/cm^3, F(000)=2352, 最终偏差因子R=0.0754, Rw=0.0710。

Thermolysis of Ru~3(CO)~1~2 and cyclopentene in octane followed by TLC has given the title cluster compounds, which have been characterized by IR, ^1H NMR, ^1^3C NMR and elementary analysis. An X-ray diffraction of the product has unequivocally established its structure. The cluster crystallizes in monoclinic space group P2~1/a, a=1.6498(8), b=1.3221(5), c=1.7330(6)nm, β=91.54(3)°, V=3779(3)nm^3, Z=8, μ=23.5cm^-^1, Dc=2.18g/cm^3, F(000)=2352 and R=0.0754, Rw=0.0710 based on 3199 independent reflections with I≥3.5σ(I).
