Di-μ-iodido-bis­[(dimethyl 2,2′-biquinoline-4,4′-dicarboxyl­ate-κ²N,N′)copper(I)]

In the centrosymmetric dinuclear title complex, [Cu₂I₂(C₂₂H₁₆N₂O₄)₂], the Cu^I atom is coordinated in a distorted tetra­hedral geometry by an N,N′-bidentate dimethyl 2,2′-biquinoline-4,4′-dicarboxyl­ate ligand and two symmetry-related I atoms, which act as bridges to a symmetry-related Cu^I atom. The distance between the Cu^I atoms within the dinuclear unit is 2.6723 (11) Å.
