Two (cAAC)₂Cu complexes, featuring a two-coordinate copper atom in the formal oxidation state zero, were prepared by reducing (Et₂-cAAC)₂Cu⁺I⁻ with metallic sodium in THF, and by a one-pot synthesis using Me₂-cAAC, Cu(II)Cl₂, and KC₈ in toluene in a molar ratio of 2:1:2, respectively. Both complexes are highly air and moisture sensitive but can be stored in the solid state for a month at room temperature. DFT calculations showed that in these complexes the copper center has a d¹⁰ electronic configuration and the unpaired electron is delocalized over two carbene carbon atoms. This was further confirmed by the EPR spectra, which exhibit multiple hyperfine lines due to the coupling of the unpaired electron with ^63,65Cu isotopes, ¹⁴N, and ¹H nuclei.
