The of the title compound, C6H5Cl2NO2S, contains two molecules with similar conformations (r.m.s. overlay fit for the non-H atoms = 0.067 Å). Atoms attached to the pendent Csp3—S bond are arranged in a staggered conformation with one of the Cl atoms anti to the C atom in the aromatic ring [C—S—C—Cl torsion angles = 178.41 (11) and −176.70 (13)°]. In the crystal, molecules are linked by C—H⋯N and C—H⋯O hydrogen bonds, generating a three-dimensional network, and weak aromatic π–π stacking is also observed [centroid–centroid separation = 3.8902 (17) Å].
Keywords: crystal structure; sulfone; pyridine derivative; hydrogen bonding; π–π stacking.

Sulfonyl groups are well-known for imparting biological activities to a lot of natural and unnatural molecules (Chen, et al., 2012; Drews, 2000; Raja, et al., 2009). Besides, halomethyl have been widely used in the preparation of a wide variety of halogenated compounds (Li & Hu, 2005; Prakash, et al., 2013; Zhao, et al., 2010). Here, we report the of 2-(dichloromethylsulfonyl)pyridine, the title compound, which may find potential use in the synthesis of interesting chlorinated compounds.
A mixture of sodium pyridine-2-sulfinate (660 mg, 4.0 mmol), chloroform (10.0 ml) and 1N KOH (5.0 ml) was refluxed over 5h. Then the orgainc layer was separated and dried over anhydrous MgSO4. Evaporation of the solvent under vacuum, followed by flash gave the title compound (white solid, 560 mg, 62 %). The obtained powder was recrystalized from ethyl acetate/hexane(1:10) solution to give colourless prisms.
The H atoms of the pyridine group were placed at calculated positions and treated as riding on the parent atoms, with Uiso(H) = 1.2Ueq(C). The dichloromethyl H atom was placed at calculated position with Uiso(H) = 1.2Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
