The title compound, C 12 H 10 ClNO 2 , was synthesized by the reaction of ethyl cyanocaetate with 4-chlorobenzaldehyde in ethanol under microwave irradiation. In the crystal structure, weak intermolecular C-HÁ Á ÁO hydrogen bonds link the molecules into centrosymmetric dimers, which are held togethe
