Neutral nickel complexes with tetradentate N-heterocyclic carbene amidate ligands for electrocatalytic hydrogen evolution†
Abstract
Neutral nickel complexes bearing tetradentate N-heterocyclic carbene (NHC) amidate ligands were prepared; the effect of the electronic properties of the ligand on the redox behavior as well as the electrocatalytic activity for hydrogen evolution reaction (HER) were investigated.
