Abstract

The reactions of the tetrahedral cluster [SeFe₃(CO)₉]^2- with some transition-metal complexes and organic halides were investigated. The mixed-metal cluster [Et₄N]₂[SeFe₂-Ru₃(CO)₁₄] (1) was obtained from the reaction of [Et₄N]₂[SeFe₃(CO)₉] with Ru₃(CO)₁₂ in acetone. Further reaction of [Et₄N]₂[SeFe₃(CO)₉] with HgI₂ produces the HgI-bridged cluster [Et₄N][SeFe₃(CO)₉(μ-HgI)] (2). While [SeFe₃(CO)₉]^2- reacts with CHPhCl₂ to produce the CHPh-bridged cluster Fe₂(CO)₆(μ-SeCHPhSe) (3), treatment with CH₂I₂ forms the major product Se₂Fe₂(CO)₆(μ-CH₂)₂ (4). Complex 1 displays an octahedral metal core with a μ₄-Se atom and two carbonyl groups bridging the Ru-Ru and Ru-Fe bonds. Cluster 2 consists of a SeFe₃ core with a HgI fragment bridging one Fe-Fe bond, and cluster 3 exhibits a Se₂Fe₂ butterfly geometry with the wingtip linked by a CHPh moiety. On the other hand, cluster 4 contains a planar Se₂Fe₂ moiety with two CH₂ groups bridging the two Se-Fe bonds. Complexes 1-4 have been fully structurally characterized by spectroscopic methods and X-ray diffraction analyses. This paper describes the formation of four different types of clusters from the reactions of [SeFe₃(CO)₉]^2- with electrophiles and discusses the role of [SeFe₃(CO)₉]^2- and the incoming electrophiles.
