4-Chloro-3-nitrobenzonitrile
Abstract
In the title compound, C7H3ClN2O2, the Cl, C and N atoms are coplanar with the aromatic ring. In the crystal structure, weak intermolecular C—H...O and C—H...N hydrogen bonds link the molecules. The π–π contact between the benzene rings, [centroid–centroid distances = 3.912 (3) Å] may further stabilize the structure.
