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.

Automated summary

Neutral triple-decker iron and cobalt complexes with a bridging 1,2-diboratabenzene ligand were synthesized by reacting a dilithium 1,2-diboratabenzene reagent with [Cp*FeCl]2 and [Cp*CoCl]2, respectively. These complexes are the first examples of the ligand bridging two metals, although 1,2-diboratabenzene metal complexes are already known.
