Unmasking the truth : The dimer [{(μ 2 ‐PNP)Co} 2 ] (Co light blue, N dark blue, P green, C gray, only one carbon atom of the isopropyl groups shown; PNP=[N{2‐P(CHMe 2 ) 2 ‐4‐MeC 6 H 3 } 2 ] − ) contains a Co 2 N 2 diamond core and bridging PNP ligands. Upon reaction with ClCPh 3 , CO, or N 2 , rearrangement of the PNP ligands to a terminal chelating mode is observed to give four‐coordinate Co complexes such as [{(PNP)Co} 2 (μ 2 ‐N 2 )].
