通过(η5-RC5H4)MCoFeS(CO)8(la:M=Mo,R=H;1b:M=Mo,R=MeO2C;lc:M=Mo,R=Me;1d:M=Mo,R=EtO2C;1e:M=W R=H)与Cp2Ni的等瓣置换反应合成了簇合物(η5-C5H5)(η5-RC5H4)MNiFeS(CO)5(2a:M=Mo,R=H;2b:M=Mo,R=MeO2C;2c:M=Mo,R=Me;2d:M=Mo,R=EtO2C;2e:M=W,R=H).进一步通过2a,b与Co2(CO)8以及2c,d与Fe2(CO)9的等瓣置换反应,分别合成了(η5-RC5H4)MoCoFeS(CO)8(la:R=H;1b:R=MeO2C)和(η5-C5H5)(η5-RC5H4)MoNiFe2S(CO)10(3a:R=Me;3b:R=EtO2C).新簇合物2c-e和3a,b的结构均经元素分析、IR及1H NMR谱学表征.此外,还对我们以前合成的一个3a,b类似物(η5-C5H5)(η5-MeO2CC5H4)MoNiFe2S(CO)10(3c)成功地进行了单晶结构分析.3c属单斜晶系,Cc(#9)空间群,晶胞参数a=1.0051(3)nm,b=1.5311(5)nm,c=1.7437 nm,β=105.5(3)°,Z=4.最终一致性因子R=0.025,Rw=0,033.
