Eo2(E=Se,Te)與Fe(CO)5在鹼性的MeOH溶液中反應後，以[Et4N]+當配對離子可產生[Et4N]Z[EFe3(CO)3]1，其中[Et4N]X[TeFe3(CO)5]結構由X-ray繞射解析得知其結構。
以[Et4N]2[SeFe3(CO)3]當起始物來研究它的親核性，與H+，Cd2+,Hg2+和Ru3(CO)12反應後分別得到[Et4N][HSeFe3(CO)9],H2SeFe3(CO)3,[{SeFE3(CO)39}2M]2-(M=Cd,Hg)及[SeFe2Ru3(CO)12]2-。從這些產物的結構中可得知Se上的孤對電子不具親核性，而是Fe-Fe鍵具親核性。
此外，亦利用Eo2(E=Se,Te)與Mn2(CO)10在鹼性的MeOH溶中反應，以Et4N+當配對離子，目前已得到[Et4N][Se2Mn3(CO)3]的結構，後續的研究正在進行中。

The reaction of Eo2(E=Se,Te) with Fe(CO)5 in basic alcoholic solution forms [EFe3(CO)9]2-.[EFe3(CO)9]2- was characterized by IR and elemental analysis, and [Et4N]2[TeFe3(CO)9] was further structurally firmed by X-ray diffraction method.
The acidification of [SeFe3(CO)9]2- with HCl(aq) give the protonated products ][HSeFe3(CO)9]- and H2SeFe3(CO)9. Further treatment of [SeFE3(CO)9]2- with M(OAc)2(M=Hg,Cd) affords the isomorphous [{SeFe3(CO)9}2M]2-.[SeFe3(CO)9]2- can react with Ru3(CO)12 to give the mixed metal cluster [SeFe2Ru3(CO)14]2- [{SeFe3(CO)9}2M]2-(M=Hg,Cd),[HSeFe3(CO)9]- and [SeFe2Ru3(CO)14]2- are structurally characterized by X-ray diffraction method.
Besides, the treatment of SeO2 with Mn2(CO)10 in basic alcogolic solution produces [Et4N][Se2Mn3(CO)9], which was characterized by IR, elemental analysis, and X-ray diffraction.
