Abstract: The title compound, [Cu₂(C₁₀H₇N₂O)₂][CuCl₂], is formulated as containing a mixed-oxidation-state [Cu₂(obpy)₂]⁺ cation (Hobpy is 2,2'-bipyridin-6-ol) and a [CuCl₂]^- anion, both of which lie on inversion centres. The mixed-valence Cu^I,II is coordinated by one O and two N atoms of two obpy ligands. The CuCu interaction [2.3805 (9) Å] results in a square-planar environment for the Cu^I,II atoms. The Cu^II atom in the anion is coordinated by two chloride ions in a linear geometry.
