Crystal structure of 4,4'-di-bromo-2',5'-dimeth-oxy-[1,1'-biphen-yl]-2,5-dione (BrHBQBr).

ABSTRACT: In the title compound, C14H10Br2O4, the dihedral angle between the aromatic rings is 67.29?(19)°. Both meth-oxy-group C atoms lie close to the plane of their attached ring [deviations = -0.130?(4) and 0.005?(5)?Å]. In the crystal, mol-ecules pack in a centrosymmetric fashion and inter-act via a mixture of weak ?-? stacking inter-actions [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.
