Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu⋯Cu separation of 6.136†(16)†à . The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43†à ) Cu⋯O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
