In the title compound, C14H10Br2O4, 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 i

In the crystal, mol­ecules pack in a centrosymmetric fashion and inter­act via a mixture of weak π–π stacking inter­actions, weak C—H⋯O hydrogen bonding, and Br⋯Br halogen bonding. This induces a geometry quite different than that predic
