氟斯替宾配合物 [CpFe(CO)(2)(SbMe2Br)][CF3SO3] 和 [CpFe(CO)(2)(SbMe2Br)][BF4] 均在阴离子和形式中性的 Sb(III) 配体之间存在显着的相互作用，同时表现出路易斯酸性和路易斯碱性。在过量配体存在下，形成了意想不到的次级产物[CpFe(CO)(Me2BrSb-mu-Br-SbBrMe2)]，强缔合的Br-阴离子桥接两个Sb供体形成四元FeSb2Br环。
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-mu-Br-SbBrMe2)] is formed in the presence of excess ligand, the strongly associated Br- anion bridging the two Sb donors to form a four-membered FeSb2Br ring.
