Accessing Osmium(VI) Nitrido Complexes with N-Heterocyclic Carbene Ligands

Key Points

• The aim is to synthesize osmium(VI) nitrido complexes with N-heterocyclic carbene ligands.
• Reacting [NBu4][OsNCl4] with Cl-IMes NHC ligands
• Using two equivalents of Cl-IMes
• Characterizing the resulting complex [OsN(Cl)3(Cl-IMes)2]
• Successful synthesis of the first osmium(VI) nitrido complexes with NHC ligands
• Formation of the neutral complex [OsN(Cl)3(Cl-IMes)2]
• Demonstrates the capability of NHC ligands in coordinating with osmium(VI)
