Abstract

This communication reports the synthesis of a new neutral and a cationic Ni(II) complex featuring a PBiP pincer ligand (BiNiCl and BiNiAcN) through oxidative addition of a Ni(0) precursor. Crystal structures revealed that the sigma-donating bismuthane exerts insignificant trans influence on the nickel. Cyclic voltammetry and orbital analysis highlight the redox-noninnocence of the PBiP ligand and potential redox-induced structural decomposition of the complexes.
