title: 4-Chloro-3-nitro-benzonitrile.
abstract: In the title compound, C(7)H(3)ClN(2)O(2), the Cl, C and N atoms are coplanar with the aromatic ring. In the crystal structure, weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules. The π-π contact between the benzene rings, [centroid-centroid distances = 3.912 (3) Å] may further stabilize the structure.
