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)

Implication

Demonstrates the synthesis of osmium(VI) nitrido complexes in a novel ligand system, indicating new pathways for metal complex development.

Abstract

The synthesis of the first osmium(VI) nitrido complexes bearing NHC ligands is described. Hereby, [NBu 4 ][OsNCl 4 ] is reacted with two equivalents of the Cl-IMes NHC to afford the neutral complex [OsN(Cl) 3 (Cl-IMes) 2 ]....
