摘要： 通过简单取代反应,合成了一个新的混金属簇合物(μ3-S)FeCo2(CO)7(dppfe) (2) (dppfe=Ph2PC5H4FeC5H4PPh2).利用IR,1H NMR,MS 和 X-ray单晶衍射的方法对簇合物2进行了结构表征.簇合物2的晶体属于三斜晶系,空间群为Pī.晶胞参数: a=1.132 4(15) nm, b=1.3670(17) nm, c=1.5769(2) nm,α=114.646(2)°,β=100.340(2)°,γ=100.113(3)°, V=2.0953(5) nm3.

Abstract: The new mixed metal cluster (μ3-S)FeCo2(CO)7(dppfe) (2) (dppfe= Ph2PC5H4FeC5H4PPh2) has been synthesized by facile substitution reaction, in which dppfe replaces two equatorial carbonyls from two Co(CO)3 groups, respectively. IR, 1H NMR, MS and X-ray crystallography characterized the new cluster 2. The cluster 2 crystallizes in triclinic space group Pī,with a=1.132 4(15) nm, b=1.367 0(17) nm, c=1.576 9(2) nm,α=114.646(2)°,β=100.340(2)°,γ=100.113(3)°,V=2.095 3(5) nm3.
