摘要：

The Lewis acidity of [(eta(5)-C5R5)Fe(CO),(BX2)] (1: R=H, X=Cl) and the robust nature of the constituent Fe-B bond have been demonstrated by reaction with 4-methylpyridine to yield the corresponding Lewis acid-base adduct. These properties have subsequently been utilised in the construction of heterodinuclear bridging borylene, bridging boryl and mu(2)-boride complexes from analogues 3 (R=Me, X=Br) and 5 (R=Me, X=Cl). All the bimetallic species so formed exhibited unprecedented coordination modes for boron.
