title: 1-(4-Chloro-phenyl-sulfon-yl)-5-(4-fluoro-phen-yl)-5-methyl-imidazolidine-2,4-dione.
abstract: The title compound, C(16)H(12)ClFN(2)O(4)S, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules are U-shaped with similar geometries and conformations. The mean planes through the benzene rings are inclined to one another by 6.07 (8)° in mol-ecule A and 8.67 (8)° in mol-ecule B. They are separated with a centroid-centroid distance of 3.9096 (10) Å in mol-ecule A and 3.9118 (10) Å in mol-ecule B. Mol-ecules A and B lie adjacent to one another, with a centroid-centroid distance of 3.7592 (10) Å between the fluoro-phenyl ring of mol-ecule A and the chloro-phenyl-sulfonyl ring of mol-ecule B and with a dihedral angle of 5.75 (8)° between the ring planes. In the crystal structure, A and B mol-ecules are linked by N-H⋯O hydrogen bonds, forming centrosymmetric dimers. These dimers stack along the [110] direction and are linked by C-H⋯O and C-H⋯F inter-actions. There are also some short halide⋯halide contacts [Cl⋯F = 3.0499 (14) and 3.1224 (13) Å, and F⋯F = 3.0612 (17) Å].
