Triple-Decker Iron and Cobalt Complexes Featuring a Bridging 1,2-Diboratabenzene Ligand.

Neutral triple-decker iron and cobalt complexes with a bridging 1,2-diboratabenzene ligand were accessed by reactions of a dilithium 1,2-diboratabenzene reagent with [Cp*FeCl] 2 and [Cp*CoCl] 2 , respectively. While 1,2-diboratabenzene metal complexes are known, these represent the first examples of the ligand bridging two metals.
