co2n2core

The Co(I) dinuclear species shown above contains a fragile Co₂N₂ diamond core capable of rearranging. For example, the complex shown above can activate N₂ both as a solid and in solution to afford the topologically linear Co-N≡N-Co core. Under vacuum or argon, the latter expels N₂ reorganizing to the bridging mode shown above. For more information about this species: Fout, A. R., etal. Angew. Chem. Int. Ed., In Press.
