Bis(μ-2,2′-bipyridin-6-olato)-κ3 N, N′: O;κ3 O: N′,N′-dicopper(I, II) dichlorocuprate(II)

The title compound, [Cu-2(C10H7N2O)(2)][CuCl2], is formulated as containing a mixed-oxidation-state [Cu-2(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,Cu-II is coordinated by one O and two N atoms of two obpy ligands. The Cu center dot center dot center dot Cu interaction [2.3805 (9) angstrom] results in a square-planar environment for the Cu-I,Cu-II atoms. The Cu-II atom in the anion is coordinated by two chloride ions in a linear geometry.
