The title compound, C10H13Cl2FN2O2S2{systematic name:N-[(dichlorofluoromethyl)sulfanyl]-N′,N′-dimethyl-N-p-tolylsulfamide}, is a well known fungicide. The dihedral angle between the mean plane of the dimethylamino group and that of the benzene ring is 32.3 (3)°. One Cl atom and one F atom of the dichlorofluoromethylthio group are disordered over two sets of sites with an occupancy ratio of 0.605 (9):0.395 (9). In the crystal structure, two C—H...Cl hydrogen bonds link adjacent molecules, forming dimers withR22(14) loops. C—H...O hydrogen bonds link pairs of dimers into chains along theb-axis direction. These chains are joined by an additional C—H...O contact, generating a sheet in theabplane.

Solvent Molecules

In the title compound, C11H11NO2, the mean planes formed by the benzene ring and the C and N atoms of the acryl group are almost orthogonal to each other, with a dihedral angle of 85.7 (1)°. During the structure analysis, it was observed that the unit cell contains large accessible voids, with a volume of 186.9 Å3, which may host disordered solvent molecules. This affects the diffraction pattern, mostly at low scattering angles. Density identified in these solvent-accessible areas was calculated and corrected for using the SQUEEZE routine inPLATON[Spek (2009),Acta Cryst.D65, 148–155]. Despite the presence of the hydroxy group in the molecule, no classical or nonclassical hydrogen bonds are observed in the structure. This may reflect the fact that the O—H group points towards the solvent-accessible void.
