Abstract: A new mixed-valence Cu^II/Cu^I complex, dark-green [CuCl(phen)₂][CuCl₂] (phen = phenanthroline, C₁₂H₈N₂), consisting of isolated [Cu(phen)₂Cl]⁺ cations and [CuCl₂]^- anions, has been synthesized under hydrothermal conditions. The [Cu(phen)₂Cl]⁺ cation contains a five-coordinated Cu²⁺ ion, coordinated by two bidentate phenanthroline ligands and a Cl atom. Each dichlorocuprate counter-ion contains a monovalent Cu⁺ ion, which occupies a special position on a twofold axis.
