Investigations of a Copper(II) Bipyridyl-N-Heterocyclic Carbene Macrocycle for CO₂ Reduction: Apparent Formation of an Imidazolium Carboxylate Intermediate Leading to Demetalation.

ABSTRACT: A copper complex supported by a redox-active bipyridyl-N-heterocyclic carbene based ligand framework is reported. From X-ray crystallography, the tetradentate macrocycle provides a distorted square planar geometry around the copper metal center. The complex was investigated for the electrocatalytic CO₂ reduction reaction (CO₂RR) in acetonitrile solutions. Electronic structure calculations were performed on the complex and associated intermediates to provide a fundamental understanding of the metal-ligand redox chemistry and are compared to the previously reported nickel and cobalt analogues. Unlike its predecessors, which are active catalysts for the CO₂RR, the copper complex decomposes under reducing conditions in the presence of CO₂. A n
