چکیده
In the title compound, C(24)H(21)BrO(3), the central bromo-methoxy-benzene ring forms dihedral angles of 63.6 (1) and 60.3 (1)° with the terminal phenyl rings, while the angle between the two phenyl rings is 25.8 (1)°. The crystal structure is stabilized by weak C-H⋯Br and C-H⋯O hydrogen bonds, and C-H⋯π and π-π stacking [centroid-centroid distance = 3.910 (3) Å] inter-actions.
