The mol-ecule of the title compound, C(23)H(20)Br(2)O(4), adopts a Z conformation as a result of inter-molecular C-H⋯Br bonding. One benzene ring, with the structure R-CHBr(2), makes a dihedral angle of 63.0 (2)° with the other benzene ring attached to the aldehyde group. Inter-molecular π-π stacking inter-actions [centroid-centroid distance = 3.698 (4) Å] and a weak C-H⋯Br contact is present in the crystal structure.
标题化合物C(23)H(20)Br(2)O(4)的分子由于分子间C-H⋯Br键合而呈Z构象。一个具有R-CHBr(2)结构的苯环与连接醛基的另一个苯环形成63.0 (2)°的二面角。晶体结构中存在分子间π-π堆积相互作用[质心-质心距离 = 3.698 (4) Å]以及弱C-H⋯Br接触。
