There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(11)Cl(2)FO(2). The F atom equally populates both meta positions of the 6-dichloro-3-fluoro-phenyl ring in each mol-ecule, resulting in 0.5 occupancy for both the F and H atoms in these positions. The dihedral angle between the mean planes of the benzene rings are 77.5 (2) and 89.8 (8)°in the two mol-ecules...
