2,6-Dichloro-3-nitropyridine

Abstract

The asymmetric unit of the title compound, C5H2Cl2N2O2, consists of two crystallographically independent mol­ecules. The pyridine ring in each mol­ecule is essentially planar, with maximum deviations of 0.004 (4) and 0.007 (4) Å. Short Cl⋯O [3.09 (3) and 3.13 (4) Å] and Cl⋯Cl [3.38 (12) Å] contacts were observed. No significant inter­molecular inter­actions were observed in the crystal packing.
