通过双齿膦配体dppe与母体簇合物(μ3-S)(μ-H)Fe2Co(CO)9进行取代反应,合成了一个新的混金属簇合物(μ3-S)(μ-H)Fe2Co(CO)7dppe.利用IR,NMR,MS等方法对新化合物进行了组成和结构表征,结果表明,在Fe2Co簇核中,两个Fe原子之间含有一个H桥,配体dppe中的两个P原子取代了Co和其中一个Fe原子上的CO.
A new mixed metal cluster (μ3-S) (μ-H) was synthesized by the substitution reaction of dppe with the parent cluster (μ3-S) ) Fe2Co (CO) 7dppe. The new compounds were characterized by IR, NMR and MS. The results show that there is one H bridge between the two Fe atoms in Fe2Co clusters, Two P atoms replace Co and CO on one of the Fe atoms.
