In the title binuclear copper(II) complex, [Cu2(ClO4)2(OH)2(C10H8N2)2], the CuII ion is coordinated in the form of a Jahn-Teller distorted octahedron by two bi­pyridine N atoms, two perchlorate O atoms and two hydroxide O atoms, and displays a distorted octa­hedral geometry. The mol­ecule belongs to the symmetry point group C2h. The CuII ion is located on a twofold rotation axis and the hydroxide and perchlorate ligands are located on a mirror plane. Within the dinuclear mol­ecule, the Cu...Cu separation is 2.8614 (7) Å. The crystal structure exhibits O-H...O, C-H...O and [pi]-[pi] [centroid-centroid distance = 3.5374 (13) Å] inter­actions.
