Crystal structure of 4,4′-di­bromo-2′,5′-dimeth­oxy-[1,1′-biphen­yl]-2,5-dione (BrHBQBr)

In the title compound, C(14)H(10)Br(2)O(4), the dihedral angle between the aromatic rings is 67.29 (19)°. Both meth­oxy-group C atoms lie close to the plane of their attached ring [deviations = −0.130 (4) and 0.005 (5) Å]. In the crystal, mol­ecules pack in a centrosymmetric fashion and inter­act via a mixture of weak π–π stacking inter­actions [centroid–centoid separations = 4.044 (2) and 4.063 (3) Å], weak C—H⋯O hydrogen bonding, and Br⋯Br halogen bonding. This induces a geometry quite different than that predicted by theory.
