文摘

The halostibine complexes [CpFe(CO)₂(SbMe₂Br)][CF₃SO₃] and [CpFe(CO)₂(SbMe₂Br)][BF₄] both contain significant interactions between the anion and the formally neutral Sb(III) ligand, which simultaneously displays Lewis acidic and Lewis basic properties. The unexpected secondary product [CpFe(CO)(Me₂BrSb-渭-Br-SbBrMe₂)] is formed in the presence of excess ligand, the strongly associated Br^{鈥?/sup> anion bridging the two Sb donors to form a four-membered FeSb₂Br ring.}
