title: 2-Chloro-5-nitro-pyridine.
abstract: The non-H atoms of the title compound, C(5)H(3)ClN(2)O(2), almost lie in a common plane (r.m.s. deviation = 0.090 Å). In the crystal, adjacent mol-ecules feature a short Cl⋯O contact [3.068 (4) Å], forming a chain; these chains are consolidated into a layer structure by non-classical C-H⋯O inter-actions.
