Abstract

In the title compound, C(22)H(18)F(2)O(3), the two fluoro-substituted rings form dihedral angles of 25.89 (15) and 55.00 (12)° with the central benzene ring. The eth-oxy group in the mol-ecule is disordered over two positions with a site-occupancy ratio of 0.662 (7):0.338 (7). In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into chains along the a axis. The crystal packing is further stabilized by C-H⋯π and π-π inter-actions, with centroid-centroid distances of 3.8605 (15) Å.
