The Lewis acidity of [(η 5 ‐C 5 R 5 )Fe(CO) 2 (BX 2 )] ( 1 : R=H, X=Cl) and the robust nature of the constituent FeB 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 μ 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.
