2,3-Dichloro-pyridine.

The complete mol-ecule of the title compound, C(5)H(3)Cl(2)N, is generated by crystallographic twofold symmetry, which forces the pyridine N atom and the opposite C-H group to be statistically disordered. In the crystal, weak aromatic π-π stacking [centroid-centroid separation = 3.805 (4) Å and slippage = 1.704 Å] leads to [100] stacks of mol-ecules. Short Cl⋯Cl contacts [3.334 (3) Å] are also observed.
