The reactions of the tetrahedral cluster[SeFe3(CO)9]2-with some transition-metalcomplexes and organic halides were investigated. The mixed-metalcluster[Et4N]2[SeFe2Ru3(CO)14] (1) was obtainedfrom the reaction of[Et4N]2[SeFe3(CO)9]with Ru3(CO)12 inacetone. Further reaction of[Et4N]2[SeFe3(CO)9]with HgI2 produces the HgI-bridged cluster[Et4N][SeFe3(CO)9(
-HgI)](2). While[SeFe3(CO)9]2-reacts with CHPhCl2 to produce theCHPh-bridged clusterFe2(CO)6(-SeCHPhSe)(3), treatment with CH2I2 forms themajorproductSe2Fe2(CO)6(-CH2)2(4). Complex 1 displays an octahedral metalcore with a 4-Seatom and two carbonyl groups bridging the Ru-Ru and Ru-Fe bonds.Cluster 2 consists ofa SeFe3 core with a HgI fragment bridging one Fe-Fe bond,and cluster 3 exhibits aSe2Fe2butterfly geometry with the wingtip linked by a CHPh moiety. Onthe other hand, cluster4 contains a planar Se2Fe2moiety with two CH2 groups bridging the two Se-Febonds.Complexes 1-4 have been fully structurallycharacterized by spectroscopic methods andX-ray diffraction analyses. This paper describes the formation offour different types ofclusters from the reactions of[SeFe3(CO)9]2-with electrophiles and discusses the role of[SeFe3(CO)9]2-and the incoming electrophiles.
