通过双齿膦配体dppe(Ph2PCH2CH2PPh2)与母体簇合物{μ3-Fc-C≡CH}Fe-Co2(CO)9(Fc=C5H5FeC5H4-)进行取代反应,合成了一个新的混金属簇合物{μ3-Fc-C≡CH}FeCo2(CO)7dppe簇合物的合成和表征.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,双齿膦配体dppe的两个膦原子取代了金属簇核FeCo2中两个Co上的羰基.
A new mixed metal cluster was synthesized by the substitution reaction of dppe (Ph2PCH2CH2PPh2) with the parent cluster {μ3-Fc-C≡CH} Fe-Co2 (CO) 9 (Fc = C5H5FeC5H4-) The synthesis and characterization of the {μ3-Fc-C≡CH} FeCo2 (CO) 7dppe cluster compounds were investigated by IR, NMR and MS methods. The results showed that the bidentate phosphine ligand dppe Of the two phosphine atoms replace the two carbonyl groups on the Co in the metal cluster core FeCo2.
