Crystal structure of 2-[(di-chloro-methane)sulfon-yl]pyridine.

The asymmetric unit of the title compound, C6H5Cl2NO2S, contains two mol­ecules with similar conformations (r.m.s. overlay fit for the non-H atoms = 0.067 A). Atoms attached to the pendent Csp 3—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) A].
