    • One of the reviewers pointed out that because of the NHC unit bearing two different N substituents, the complex 10 b contains a chirality axis formed by the Ir-C bond as an additional chirality element (see, e.g.:, D.

However, no experimental evidence for the formation of diastereomeric complexes was found. The conformation around the Ir-C bond is likely dictated by the geometric constraints of the chelate ring, which favor the geometry found in the crystal structure and destabilize other conformers.
