title: Tuning the electronic properties of an N-heterocyclic carbene by charge and mesomeric effects.
abstract: N-Methylation of a pyridoimidazolium salt and subsequent deprotonation afford a cationic NHC ligand. The spectroscopic characteristics of its Rh and Ir metal complexes reveal the reduced donor and enforced π-acceptor behaviour of this ligand system.
