A μ‐η⁶: η⁶‐1,3,5‐Triboratabenzenebis(cyclopentadienylcobalt) Triple‐Decker Complex

Abstract

A CpCo‐induced hydrogen migration and elimination in 1 gives rise to the olive‐green, paramagnetic triple‐decker complex 2 with the new 1,3,5‐triboratabenzene bridging ligand. The B3C3 ring is planar and the BC distances almost the same length. Compound 2 may be easily oxidized with AgBF4 to the diamagnetic 2+BF −4.
