Abstract

The electrochemical properties of two Ni(NNN)X₂ pincer complexes are reported where X = Cl or Br and NNN is N,N′-(2,6-diisopropylphenyl)bis-aldiminopyridine. Cyclic voltammetry under 1 atm of CO₂ suggests electrocatalytic CO₂ reduction activity, however, bulk electrolysis shows a poor Faradaic efficiency for CO evolution with a high Faradaic yield for H₂ evolution.
