In the title compound, C12H9Cl2NO3, which is the fungicide vinclozolin, the dihedral angle between the oxazolidine ring mean plane [r.m.s. deviation = 0.029 Å] and the benzene ring is 77.55 (8)°. In the crystal, mol­ecules are linked via C—H...O hydrogen bonds, forming chains along [010]. The chains are linked by short Cl...Cl contacts [3.4439 (3) and 3.5798 (3) Å], resulting in a three-dimensional architecture.

The title compound, C21H11ClF6N2O3 (systematic name: 1-{4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-fluorophenyl}-3-(2,6-di­fluoro­benzo­yl)urea), is a benzoyl­urea pesticide. The dihedral angles between the central fluoro­benzene ring and the terminal di­fluoro­phenyl ring and chloro­phenyl ring system are 62.15 (5) and 88.03 (5)°, respectively. In the crystal, N—H...O hydrogen bonds link adjacent mol­ecules, forming R22(8) inversion dimers that pack into loop chains along the a-axis direction by short F...F contacts [2.729 (2) Å]. In addition, the chains are linked by weak C—H...π and π–π inter­actions [inter-centroid distances = 3.661 (2) and 3.535 (12) Å], resulting in a three-dimensional architecture.
