Abstract:
In the title compound, C(28)H(19)BrF(2)O(2), the central benzene ring makes dihedral angles of 62.51 (18), 46.23 (18) and 48.19 (18)° with the bromo-substituted benzene ring and two terminal fluoro-substituted benzene rings, respectively. In the crystal, mol-ecules are linked by C-H⋯F hydrogen bonds into infinite chains along [110]. Weak C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.683 (2) Å] also occur and short inter-molecular F⋯F contacts [2.833 (4) Å] are observed.
