In the title molecule, C 14 H 8 IN 3 O 2 , the cyanide group is anti to the iodide substituent of the adjacent benzene ring. The central segment is essentially planar (r.m.s deviation = 0.0341 Å) and it is twisted away from the iodide- and nitro-substituted benzene rings by 69.02 (9) and 15.83 (16)°, respectively. In the crystal, molecules are linked by weak C—H...N interactions, leading to C (8) chains along [010].
