Type: article
Abstract: A series of Ir–(κ2‐NSi) complexes with 2‐quinolone type ligands have been prepared and characterized to increase our scope of 16e unsaturated Ir–(κ2‐NSi) species to carry out a comprehensive study of the nature of the IrSi bond. Density functional theory calculations with natural bond orbital and quantum theory of atoms in molecules analyses of a range of Ir–silyl(ene) complexes allows the description of the IrSi bond of the examinated complexes as a polarized covalent interaction. The findings of this study also suggest that the most accurate description of this bond in the Ir–(κ2‐NSi) complexes is base‐stabilized silylene. Investigating the silicon environment has been the key for determining the nature of the IrSi bond. This insight also enables to elucidate the base‐stabilized TM–silylene character in other complexes.
