description The asymmetric unit of the title compound, C20H18F2N2O2S, contains four independent molecules, two of which are paired into a dimer by way of two N—H...S hydrogen bonds. The other two independent molecules are paired into two centrosymmetric dimers via pairs of intermolecular N—H...S hydrogen bonds. In one molecule, the carboxylate O atoms, methylene and methyl groups attached to the benzene ring are disordered between two positions in a 0.908 (3):0.092 (3) ratio. In two of the independent molecules, the F and H atoms of the diflourophenyl ring are flip-flop disordered (i.e. by 180° about the C—C bond axis linking the ring to the rest of the molecule) in a 3:2 ratio. The crystal packing is stabilized by weak intermolecular C—H...O hydrogen bonds.
